مسيرته الكروية
بدايته المبكرة
بدأ بول بوغبا حياته الكروية في السادسة من عمره، مع نادي يو إس لبري رواسي، الذي يبعد أميال قليلة عن مسقط رأسه، و في تلك الفئة أمضى سبعة مواسم، قبل أن يشغل منصب قائد فئة تحت 13 سنة، و بعد موسم واحد بدأ بوغبا مسيرته مع نادي لوهافر، و كان بوغبا في موسمه الثاني هناك قائداً لفئة تحت 16 سنة، و وصل معهم إلى المرحلة النهائية من البطولة الوطنية لتحت 16 سنة، تم استدعاء بوغبا في ذلك الوقت ليشارك مع المنتخب تحت 16 سنة، وانتقل ليلعب مع مانشستر يونايتد.

مانشستر يونايتد
لم يكن انتقال بوغبا إلى مانشستر يونايتد قصةً سهلة، فحسب نادي لوهافر إن مانشستر يونايتد لم يقوموا بما يجب القيام به لنقل لاعبهم، بل اتجهوا لمفاوضة والدي بوغبا من أجل نقل ابنهم، و في أغسطس 2009، أصدروا بياناً رسمياً انتقدوا فيه طريقة مانشستر يونايتد و عائلة بوغبا كذلك، و هددوا بتصعيد الأمور إلى الفيفا، و بالفعل قام نادي لوهافر بشكوة مانشستر يونايتد إلى الفيفا و اتهموا بوغبا بالذهاب إلى إنجلترا من أجل الأموال، و هو ما نفاه اللاعب قبل أن تقوم الفيفا بتبرئة مانشستر يونايتد من أي تهمة نظراً لعدم ارتباط بوغبا مع ناديه الفرنسي بأي عقود أو أوراق. انتهى الانتقال الرسمي لمانشستر يونايتد في أكتوبر 2009، و شارك لأول مرة مع فريق تحت 18 سنة في نفس الشهر ضد كرو ألكسندرا و هزموا 2–1، انهى بوغبا موسم 2009–10 بـ 21 مباراة و 7 أهداف، في موسم 2010–11، تم استدعاء بوغبا لأول مرة إلى الفريق الرديف لمانشستر يونايتد تبعها عدة استدعاءات، و سجل العديد من الأهداف هناك، في فبراير 2011، بوغبا كان واحد من أربع لاعبين في الفريق الرديف تمت ترقيتهم إلى الفريق الأول لمانشستر من قبل السير أليكس فيرغسون قبل مباراة المان يونايتد ضد كراولي تاون في كأس الاتحاد الإنجليزي لكرة القدم، و حصل بوغبا على القميص رقم 42، و لكنه لم يشارك في المباراة، و لكن تم استدعاءه مرة أخرى ليكون على مقاعد البدلاء في إحدى جولات البريميرليغ ضد وولفرهامبتون واندررز، و لكنه لم يشارك كذلك، و بسبب عدم مشاركته تم إعادة إرساله إلى الفريق الرديف. في موسم 2011–12، أكد السير أليكس فيرغسون أن بوغبا سيتم ترقيته ليلعب مع الفريق الأول، و قال ” إذا لم نعتمد على بوغبا، ماذا سيحصل؟ سيذهب إلى فريق آخر، لذلك يجب علينا منحه فرصة في الفريق الأول ” إلا أنه بقي مع الفريق الرديف، و في سبتمبر 2011 تم استدعاءه للمشاركة مع الفريق الأساسي ضد ليدز يونايتد، و كانت أول مشاركاته الرسمية في الفريق الأول حينما شارك كبديل في تلك المباراة التي فاز بها مانشستر يونايتد 3–0، و شارك بوغبا للمرة الثانية ضد آلدريشوت تاون في الدور الرابع من كأس رابطة الأندية الإنجليزية المحترفة في أكتوبر 2011. في يناير 2012، شارك بوغبا لأول مرة في البريميرليغ ضد ستوك سيتي، بعد خروج هيرنانديز في الدقيقة 72، و شارك مرة أخرى ضد ويست بروميتش ألبيون في مارس 2012، و بعد أربعة أيام شارك بوغبا في مباراة فريقه ضد أتلتيك بيلباو في الدوري الأوروبي بعد دخوله كبديل.

يوفنتوس
في 3 يوليو 2012، أكد أليكس فيرغسون أن بوغبا قد غادر النادي بعد عدم تجديد عقده، وقال السير أليكس فيرغسون «أن بوغبا قد اتجه إلى يوفنتوس و منذ وقت طويل حسب الاخبار التي تصلنا»، و على موقعه الرسمي أكد اليوفنتوس أن بوغبا خضع للفحوص الطبية في النادي و في أغسطس اكملت عملية الانتقال للنادي الإيطالي، و كان أول ظهور له ضد بنفيكا في المباراة الودية التي لعبها النادي ودخل بديلا عن بيرلو في الدقيقة 78، كما شارك في بطولة تيم الودية و ضد ميلان في بطولة كأس برلوسكوني، و قدم أداءً كبيراً جعله محط أنظار الجميع حتى الصحافة في بلده فرنسا، حتى أن أحد المشجعين رفعة لافتة يقول فيها ” إنه باتريك فييرا الجديد “. شارك في بداية الموسم كآحتياطي بديل لثلاثي الوسط ماركيزيو بيرلو وفيدال وتمكن من تقديم اداء لافت للنظر مع البيانكونيري في الكالتشو ودوري ابطال أوروبا، تمكن من تسجيل أول اهدافه مع يوفنتوس بعد أن شارك بديلا لبيرلو عند نهاية مباراة نابولي – يوفنتوس وتمكن من تسجيل الهدف من كرة مرتدة من الدفاع ليسددها قوية ويسجل أول اهدافه، لعب في المباراة التالية في الدوري كأساسي ضد بولونيا بسبب غياب فيدال للايقاف وماركيزيو للاصابه، تمكن من صنع الهدف الأول لجياكيريني وكوالياريلا بطريقة جميلة، وتسجيل هدف الفوز في الدقيقة 92 برأسية بعد توزيعة من سيباستيان جيوفينكو، وقد سجل هدف آخر برأسية ولكن الحكم لم يحتسبة حيث احتسب خطأ لفريق بولونيا.

العودة إلى مانشستر يونايتد
2016–18: الفوز بالدوري الأوروبي والأداء المتذبذب
في 8 أغسطس 2016، وقع بوغبا مع مانشستر يونايتد على عقدٍ مدته 5 سنوات مقابل مبلغ قياسي قدره 105 مليون يورو، متخطيًا بذلك حامل الرقم القياسي السابق غاريث بيل. تلقى وكيل بول بوغبا، مينو رايولا، مبلغ 27 مليون يورو من يوفنتوس بسبب عودته إلى مانشستر يونايتد؛ كشف يوفنتوس عن رسوم إضافية بلغت 26.154 مليون يورو. أعلن اتحاد كرة القدم أن بوغبا سيتم إيقافه في المباراة الافتتاحية لمانشستر يونايتد في الدوري الإنجليزي الممتاز لموسم 2016–17 ضد بورنموث، بسبب حصوله على بطاقتين صفراء في نسخة الموسم السابق من كأس إيطاليا مع يوفنتوس. في 19 أغسطس، لعب أولى مبارياته مع الفريق، وذلك في مباراة في الدوري ضد ساوثهامبتون انتهت بفوز المان يونايتد بثنائية نظيفة.
بعد الهزيمة 1–2 على أرضه في أول مشاركة له في ديربي مانشستر في 10 سبتمبر، تم انتقاد بوغبا بسبب افتقاره إلى الانضباط في التمركز من قبل النقاد جيمي كاراغر. في 24 سبتمبر، سجل بوغبا أول هدف له مع مانشستر يونايتد ضد حامل اللقب ليستر سيتي في مباراة انتهت بنتيجة 4–1 لمصلحة الشياطين الحمر. يوم 20 أكتوبر، سجل الفرنسي هدفين ضد فنربخشة التركي في مباراة في مرحلة مجموعات الدوري الأوروبي انتهت بنتيجة 4–1.

في يناير 2017، سجل بوغبا في مباراة الهزيمة 2–1 خارج أرضه أمام هال سيتي في مباراة الإياب من نصف نهائي كأس رابطة الأندية الإنجليزية المحترفة، مما سمح لمانشستر يونايتد بالتقدم إلى النهائي بعد الفوز بنتيجة 3–2 في مجموع المباراتين. في 24 مايو 2017، لعب بوغبا في نهائي الدوري الأوروبي وسجل الهدف الأول عند الدقيقة الـ18 من ضد النادي الهولندي أياكس، في المباراة التي أنتهت بفوز اليونايتد بنتيجة 2–0 حيث فاز مانشستر يونايتد بأول كأس قاري منذ 9 سنوات. أنهى مانشستر يونايتد موسم دوري 2016–17 في المركز السادس، مع مشاركة بوغبا في 30 مباراة، وسجل خمسة أهداف وقدم أربعة تمريرات حاسمة.

في 13 أغسطس 2017، سجل بوغبا الهدف الرابع في المباراة التي فاز فيها اليونايتد بنتيجة 4–0 على وست هام يونايتد في نهاية الأسبوع الافتتاحي لموسم الدوري الممتاز 2017–18. خلال هزيمة بازل 3–0 في مرحلة المجموعات في دوري أبطال أوروبا 2017–18، تمزقت أوتار الركبة اليسرى عند بوغبا، وكان من المتوقع أن يغيب عن ثماني مباريات في الدوري. عاد إلى اللعب في 18 نوفمبر في مباراة الفوز 4–1 على نيوكاسل يونايتد، وصنع هدف أنتوني مارسيال مع كرة عرضية من الجناح وسجل هدف يونايتد الثالث. في أول مباراة له في عام 2018، في 1 يناير، قدم بوغبا تمريرات حاسمة لكلا هدفي فوز يونايتد على إيفرتون 2–0. طوال الأشهر القليلة المقبلة، كان بوغبا مرة أخرى موضع انتقادات فيما يتعلق بنقص الانضباط وعدم إلتزامه بواجباته الدفاعية. كان غائبًا عن العديد من المباريات المهمة، بما في ذلك فوز مانشستر يونايتد 2–1 على غريمه ليفربول، وكان يدخل فقط كبديل في وقت متأخر حيث تم اقصاء فريقه من دوري أبطال أوروبا في دور الـ 16 في مارس.

في اليوم السابق لديربي مانشستر، صرح بيب غوارديولا مدرب مانشستر سيتي أن وكيل بوغبا، مينو رايولا، قد عرض على بوغبا أن يلعب لصالح فريقه، وهو ما أنكره رايولا. في الديربي على ملعب الاتحاد في 7 أبريل، سجل بوغبا هدفين في متتاليين حيث عاد مانشستر يونايتد لهزيمة خصمه 2–3 بعد أن سجل هدفين في الشوط الأول. كما منع مانشستر سيتي من حسم لقب الدوري الممتاز ضدهم، وهو ما فعلوه فيما بعد حيث أنهى مانشستر يونايتد الموسم كمركز ثاني. في نهائي كأس الاتحاد الإنجليزي 2018 ضد تشيلسي، هُزم فريقه 1–0، حيث أهدر بوغبا فرصة للتعادل برأسه في منطقة الجزاء.

2018–الآن: عودة أدائه المعروف
نظرًا لغياب قائد الفريق أنتونيو فالنسيا، تولى بوغبا قيادة الفريق مؤقتًا للنادي في المباريات الافتتاحية لموسم 2018–19. بدأ بوغبا الموسم جيدًا في الأسابيع القليلة الأولى، حيث سجل أربعة أهداف بصفته اللاعب الجديد الذي يُنفذ ضربات الجزاء. ولكن بعد سلسلة من النتائج المخيبة للآمال، أعلن مورينيو أن بوغبا لن يتولى قيادة الفريق مرة أخرى. في أواخر سبتمبر، تم تصوير بوغبا ومورينيو وهم في مواجهة في أحد الدورات التدريبية، على الرغم من تأكيد مورينيو أنه "لا توجد مشكلة" بين الاثنين. على الرغم من هذا، واصل بوغبا اللعب في كأساسي وسجل في فوز يونايتد 2–1 على إيفرتون. ومع ذلك، بعد موجة من سوء الأداء والعلاقة المتوترة مع مورينيو، وجد بوغبا نفسه عرضة للخروج من مانشستر يونايتد خلال موسم الانتقالات في يناير. استمر بوغبا على مقاعد البدلاء طوال المباريات القليلة التالية حتى وشملت مباراة يونايتد ضد ليفربول حيث خسر مانشستر يونايتد 1–3. بعد وقت قصير من هذه المباراة، تمت إقالة مورينيو من تدريب مانشستر يونايتد، وتم تعيين أولي جونار سولسكير كمدير فني مؤقت بعد يوم واحد. تحت المدير الفني الجديد، أولي جونار سولسكير، شهد بوغبا إحياء لأداءه حيث سجل هدفين على في مباراتين متتاليتين ضد هدرسفيلد تاون وبورنموث. في يناير 2019، صنع بوغبا هدف ماركوس راشفورد في مباراة الفوز على توتنهام هوتسبير، بأهداف متتالية في المباريات التالية ضدبرايتون أند هوف ألبيون وبيرنلي. ثم سجل بوغبا ثنائية في الفوز 3–0 خارج أرضه على فولهام، وحصل على لقب رجل المباراة؛ بفضل هدفيه وصل أفضل رصيد من الأهداف في موسم واحد في مسيرته بـ11 هدف في الدوري و13 في جميع المسابقات. واصل بوغبا هذا الاتجاه بتسجيله هدفًا آخر في مباراة الفوز 2–0 في كأس الاتحاد الإنجليزي في الجولة الخامسة أمام تشيلسي.

بطريق

بطريق

البِطْرِيق (باللاتينية: Spheniscidae) أو (بالإنجليزية: Penguin)هو نوع من الطيور البحرية غير القادرة على الطيران تعيش في النصف الجنوبي للكرة الأرضية، خصوصاً في القارة القطبية الجنوبية. لدى البطاريق تكيُّف عالٍ مع الحياة في الماء، إذ إن ريشها أبيض وأسود اللَّون يساعدها على التمويه بينما تحوَّلت أجنحتها إلى زعانف لتساعدها على السباحة. تتغذى مُعظم أنواع البطاريق على الكريل والحبار والسمك وأشكال الحياة البحريَّة الأخرى التي تصطادها أثناء الغطس تحتَ المياه. تقضي هذه الطيور نصفَ حياتها تقريباً على اليابسة، بينما تقضي النصف الآخر تحت الماء.

مع أنَّ وجود البطاريق في العالم منحصرٌ بالنِّصف الجنوبي من الكرة الأرضية، إلا أنَّ أنواعاً قليلةً منها فحسب تعيش في قارة أنتاركتيكا. ففي الواقع تقطن العديد من البطاريق منطقة المناخ المعتدل على سواحل أستراليا وإفريقيا وأمريكا الجنوبية، بل وإنَّ أحد أنواعها (وهو بطريق الغالاباغوس) يعيش على مسافةٍ غير بعيدة من خط الإستواء.

أضخم نوعٍ باقٍ على قيد الحياة من هذه الطيور هو البطريق الإمبراطوري، إذ يبلغ طول الطير البالغ منه 1.1 متر ويزن 35 كيلوغراماً أو أكثر. و من جهة أخرى أصغر نوع حي هو البطريق القزم، الذي لا يتعدى طوله 40 سنتيمتراً بينما يزن نحو كيلوغرام واحد. بصورة عامة، تميل البطاريق الأكبر حجماً إلى العيش في بيئات أكثر برودة، بينما تقطن البطاريق الصَّغيرة بيئات معتدلة أو مدارية، في ظاهرة تسمى مبدأ بيرغمان. كانت بعض الأنواع قبل التاريخية من البطاريق ضخمةً جداً في الحجم، إلى حدِّ أنها كانت تقارن في حجمها ووزنها بإنسانٍ بالغ.
البنية والمظهر
اختلاف الحجم والوزن لدى البطريق ملحوظ، لكن البنية الجسمية وكساء الجلد قد يكون مختلفاً لتواجد الشعر الذي يغطي جسمه.

الغذاء والسلوك
تبحث البطاريق عن غذائها في الماء حيث تتغذى على الأسماك والسرطانات والحبارات.. ونظراً لأنها تستهلك كميات كبيرة من الطعام فهي تلجأ للمياه التي تتوافر بها تجمعات كبيرة من الغذاء بشرط أن تكون هذه المياه آمنة من الحيوانات التي تتغذى على البطاريق مثل الفقمة والحيتان. يقضي البطريق معظم حياته في المحيطات، ويتميز بوقفته العمودية ومشيته الهادئة؛ لأن لديه أرجلاً قصيرة وجسماً طويلاً منتفخاً، وعلى الرغم من أن البطاريق تمشي بطريقتها الشهيرة الصعبة إلا أنها تستطيع المشي بسرعة الإنسان وبإمكانها أيضاً تسلق المنحدرات الصخرية، والوثوب من صخرة إلى أخرى بيسر ومهارة، وبعض البطاريق لديها القدرة على التزحلق على الثلج أو الجليد عن طريق الهبوط فجأة وبشدة مستخدمة الانزلاق على بطونها. تستطيع السباحة مدة عشر ساعات بسرعة 13 كيلو مترا في الساعة .. لكنها تقفز للتنفس كل دقيقة خارج الماء، جسم البطريق ملائم جداً للعيش في البحر؛ لأنه مغطى بريش قصير وسميك كأنه معطف واقٍ من الماء، كما أن الجناحين يقومان بوظيفة الزعانف، إضافة إلى وجود طبقات دهنية سميكة تساعد على تدفئتها في الماء الباردة. أما مساكن البطاريق فهي عبارة عن أعشاش محفورة تحت الصخور الكبيرة أو الشجيرات.. أما البطريق الملك والامبراطور فلا يحتاج لبناء أعشاش وهو يقوم بتدفئة البيض والصغار بإبقائهم تحت ثنية في منطقة البطن وبحملها على الأرجل

الحجم والوزن
قد يصل طول البطريق القزم (Eudyptula minor) إلى حوالي 30 سم ووزن نصف كيلوغرام، وبالمقابل يُعد البطريق الإمبراطوري (Aptenodytes forsteri) بطول قد يصل إلى 1,20 متر ووزن حتى 40 كيلوغرام، الأكبر في فصيلة طيور ذات الفك الجديد. هذا الاختلاف في الطول يُفسر عبر قاعدة بيرجمان (Bergmann's Rule)، حيث يُمثل البطريق فيها أفضل مثال. أغلب الأنواع تزن حوالي ما تزنه أحجامها ماء، مما يُسهل عليهم عملية الغوص. ويقتات على الكائنات البحرية والأسماك الصغيرة يعيش في القارة المتجمدة الجنوبية وأمريكا الجنوبية وأستراليا وأفريقيا.

الأنواع
يعيش اليوم 17 نوعًا من البطاريق في العالم، ومنها:

البطريق الإمبراطوري.
البطريق الأفريقي.
البطريق القزم.
بطريق جينتو.
البطريق الملكي.
بطريق آديلي.
درجة الحرارة
تمضي البطاريق الكثير من الوقت للتعامل مع درجة الحرارة، وهي من الحيوانات ذات الدم الحار تماما مثل الإنسان بدرجة حرارة جسم طبيعية (100 درجة فهرنهايت - 38 درجة مئوية). إذاً كيف يستطيع البطريق البقاء دافئا في الأماكن الباردة وفي المياه الجليدية الباردة؟ تماما مثل الحيتان، فإن جسم البطاريق يحتوي على طبقة من الدهون تحت الجلد تسمى "دهن الحوت"، ويعلو هذه الطبقة ريش كالزغب يعلوه الريش الخارجي؛ مما يجعلها تشعر بالدفء. كما تطلق بعض الغدد في جسم البطريق زيتا يغطي ريشه، ويجعل جسمه مقاوما للماء والريح. ومع ذلك، تظل البطاريق بحاجة للبقاء دافئة، لذلك غالبا ما تسير البطاريق جنبا إلى جنب في مجموعات مع إبقاء أجنحتها مضمومة إلى جسمها للمحافظة على دفء أجسامها. وقد تصل أعداد البطاريق إلى 5000 في المجموعة الواحدة. تعاني بعض البطاريق من مشكلة عكسية: تعيش بطاريق الأباغوس في المناطق الاستوائية الحارة جدا، وتقوم هذه البطاريق بمد أجنحتها وزغب ريشها للتبريد.

التزاوج
عندما يفكر ذكر البطريق في الزواج، يسير فوق الجليد على غير هدى متفحصاً كل ما يمر أمامه من إناث جنسه باحثاً عن فتاة أحلامه لهذا فهو يسير منتصب القامة منتفخ الصدر شارد النظرات. ولكنه إذا ما شاهد إحدى الاناث الجميلات تقبل ناحيته فإنه يعتدل ويرسل إليها إشارات جانبية، إذا ما مرت بجانبه دون اهتمام ولكنه يلتفت إليها بكبرياء، وإذا رضيت يبدأ بالعدة لخطبتها، وهنا يبدو غريب الأطوار هذا ما أكده عالم الطبيعة« د. كونور» الذي يقول: إن كثيراً من الحيوانات تعرف فترة الخطوبة ومنها طائر البطريق. تتخذ البطاريق رفيقا واحدا طوال حياتها ويقوم ذكر البطريق بتقديم حجرة ملساء للأنثى كرمز لطلب يدها.

عبد الحق نوري

عبد الحق نوري

عبد الحق النوري الملقب ب "Appie" (مواليد 2 أبريل 1997 في أمستردام) هو لاعب كرة قدم هولندي من أصل مغربي كان يلعب في مركز الوسط المهاجم ثم عدة مواقع مختلفة مع نادي أياكس أمستردام الهولندي، ومنتخب هولندا تحت 21 سنة لكرة القدم.

كان النوري جزءًا من الجيل الذهبي لنادي أياكس أمستردام في منتصف عام 2010 رفقة اللاعبين دوني فان دي بيك وفرينكي دي يونغ وماتيس دي ليخت. بقيادة المدرب إيرك تين هاغ.

في 8 يوليو 2017 وهو في ربيعه ال20، انهار عبد الحق نوري بعد سقوطه خلال مباراة ودية ضد فريق فيردر بريمن حيث أصيب بنوبة قلبية أدخلته في غيبوبة اصطناعية، مما تسبب له بتلف خطير ودائم في الدماغ أقعده عن ممارسة كرة القدم للأبد. وعلى الرغم من حالته، فقد أدرج نوري كلاعب في الفريق الأول لنادي أياكس قبل بداية موسم 2017–18.

بالإضافة إلى جنسيته المغربية، انضم اللاعب إلى نادي أياكس أمستردام في سن السابعة وأصبح أصغر لاعب يفوز بلقب أفضل لاعب في الدوري الهولندي لكرة القدم للدرجة الثانية مع الفريق الاحتياطي Jong Ajax التابع لنادي أياكس أمستردام. خلال مسيرته الاحترافية، التي استمرت أقل من ثلاث سنوات، شارك نوري في ستة انتصارات لنادي أجاكس في الدوري الهولندي الممتاز وهو نائب بطل البطولة خلال موسم 2016-2017.

يعد النوري أفضل هداف في التاريخ في فئة منتخب هولندا تحت 19 سنة لكرة القدم برصيد تسعة أهداف. وقد كان قبل إصابته على وشك الاختيار الدولي للعب مع هولندا أو المغرب.
ولد الأب محمد نوري في مدينة طنجة ثم هاجر إلى هولندا في عام 1990 لمواصلة دراسته في مجال المعلوماتية في جامعة أمستردام، لكنه سرعان ما تزوج من مغربية من مدينة تطوان، وتوقف عن الدراسة ليبدأ العمل في متجر للجزارة في منطقة غوزينفيلد في أمستردام، وهي منطقة كان يقطنها بكثرة المهاجرون المغاربة في الفترة ما بين 1970 إلى 1995. ولد بعدها عبد الحق النوري في 2 أبريل/نيسان 1997 وترعرع ضمن عائلة مغربية مسلمة مكونة من سبعة أطفال (أربع فتيات وثلاثة أولاد).. فكان نوري متدينًا منذ نعومة أظافره، حيث بدأ الصلاة مبكرًا وهو في السابعة من عمره بالموازاة مع دراسته. وبفضل شعبية شقيقيه الكبيرين محمد وعبد الرحيم في الحي والمعروفان بممارستهما لكرة القدم، سار عبد الحق النوري على دربهما وبدأ يلعب كرة القدم بانتظام مع أصدقائه في ساحة نوري في أمستردام الغربية. حيث كان شقيقه محمد نوري لاعبا في نادي SV TEC الهولندي للدرجة الثالثة.

التحق عبد الحق النوري بواسطة والده وفي سن مبكرة بناديين للهواة في المدينة وهما نادي SC Eendracht '82 ونادي RKSV DCG. وقد تم رصد الشاب في سن السابعة من قبل مكتشفي المواهب التابعين لنادي أجاكس أمستردام الذين قاموا بتجنيده مبكرًا ضمن صفوف الفريق.. ليلعب عبد الحق نوري في جميع فئات شباب أياكس أمستردام تحت إشراف المدرب ديفيد إندت.

في أبريل 2007، شارك نوري في بطولة كأس العالم المصغرة للمنتخبات (موندياليتو) التي تقام في منطقة الغرب في البرتغال. ومن بين الفرق المنافسة لعب "أبي" ضد فريق مراكشي مغربي حيث سجل هدفين، لكن أداءه في المباراة كان مخيبا للآمال مما أثار موجة من السخط والغضب ضده في المدرجات سواء من قبل المشجعين أوآباء اللاعبيين في نادي أياكس حيث صرح أحدهم «"إنه يلعب بشكل سيئ لأنه يلعب ضد المغاربة."»

سطع نجم "أبي" في الصحف وهو في ربيعه الثالث عشر فقط كان أولها صحيفة هيت بارول الهولندية. في عام 2012، شارك في بطولة مارفيلد (Marveldtoernooi)، وهو نوع من كأس أوروبا يجمع أكبر الأندية في أوروبا تحت فئة 16 سنة، حيث أنهي المسابقة بالحصول على جائزة أفضل لاعب في المسابقة. في سن الرابعة عشر، كان عبد الحق النوري يقضي مساءه بعد انهاء تداريبه في مجزرة والده بالحي. في عام 2013، توقف والده عن العمل في متجر الجزارة لأسباب صحية.

في أبريل 2014، جذب الانتباه اليه كموهبة بارزة حيث تم اختياره كأحد أفضل اللاعبين في كأس المستقبل. ثم تم اختياره كواحد من أفضل 40 لاعباً شاباً ولدوا عام 1997 من قبل صحيفة الغارديان. وذلك قبل أن يبدأ مشواره الإحترافي.

في نوفمبر 2014، دعاه المدرب فرانك دي بوير للتدرب مع الفريق الأول. وخلال نافذة الانتقالات الشتوية لموسم 2015-2014، تمت دعوته مرة أخرى مع اللاعب دوني فان دي بيك للتدرب مع فريق أياكس أمستردام الأول في دولة قطر. وبفضل أدائه الجيد مع فئة الشباب تحت سن 19 سنة، سُمح له بالتدرب يومياً مع الفريق الأول. بعد شهر، مدد عبد الحق عقده مع النادي حتى منتصف 2018، وخلال ذلك شارك مع فريق أياكس أمستردام تحت سن 19 سنة في الدوري الأوروبي للشباب، حيث برز نجمه على الساحة الأوروبية في المباريات ضد نادي برشلونة وباريس سان جيرمان.

المسيرة الكروية
محليا
أياكس
نوري هو من خريجي أكاديمية الشباب لنادي أياكس. شارك في أول مباراة رسمية له مع الفريق الاحتياطي لأياكس في 13 مارس 2015، في مباراة بدوري الدرجة الثانية الهولندي ضد في في في فينلو، حيث دخل كبديل عن داني باكر في الدقيقة 78 من مباراة الخسارة 1–0.

في 21 سبتمبر 2016، شارك نوري في أول مباراة رسمية له مع الفريق الأول لأياكس في كأس هولندا ضد فيلم تو تيلبورغ، وسجل هدف. بسبب أداءة مع رديف أياكس خلال الموسم حصل على جائزة لاعب الموسم 2016–17 في دوري الدرجة الثانية الهولندي، فضلا عن ترقيته للفريق الأول.

دوليا
الاختيار بين هولندا والمغرب (2014-2017)
في 9 أكتوبر 2014، تم استدعائه للعب مع منتخب هولندا تحت 19 سنة لكرة القدم. في ذلك الوقت، كان نوري يحمل الجنسية المغربية ومستقطب من قبل الجامعة الملكية المغربية لكرة القدم.

لعب النوري مباراته الدولية الأولى ضد منتخب أندورا لكرة القدم تحت 19 سنة في تصفيات بطولة كأس الأمم الأوروبية 2015 تحت 19 سنة. حيث تمكن من تسجيل هدفين والفوز رفقة فريقه بحصيلة ضخمة 7 أهداف مقابل 0، لكنه لم يستطع تجاوز مرحلة المجموعات في هذه المسابقة، فتابع عبد الحق المشاركة في عدد من المباريات رفقة منتخب هولندا تحت 19 سنة لكرة القدم حيث تمكن من تسجيل 9 أهداف في 23 مباراة مما أهله إلى التصفيات المؤهلة لنهائيات كأس الأمم الأوروبية 2016 تحت 19 سنة.

في حين أن العديد من الهولنديين المغاربة كانوا يختارون اللعب دوليا لصالح أسود الأطلس. فحاول الناخب الوطني هيرفي رينارد، توجيه دعوة لعبد الحق نوري للانضمام إلى الفريق الأولمبي المغربي تحت 23 سنة بقيادة الهولندي مارك ووت، لكن الأخير رفض الدعوة، مفضلاً مواصلة حملته الأوروبية بعد التأهل لبطولة أمم أوروبا تحت 19 سنة 2016. شارك نوري في المسابقة التي فاز بها بكل سهولة منتخب فرنسا تحت 19 سنة لكرة القدم. وبتسجيله هدفا ضد منتخب ألمانيا تحت 19 سنة لكرة القدم في التصفيات، حيث كان قائد المنتخب طوال سلسلة مبارياته في المسابقة التي تعرف خلالها على اللاعب الفرنسي عثمان ديمبيلي الذي سرعان ما أصبح صديقًا مقربا له.

التقاعد الاضطراري
في 8 يوليو 2017 أصيب عبد الحق نوري بتلف خطير ودائم في الدماغ بعد سقوطه خلال مباراة ودية في النمسا. وقد صرح نادي أياكس في بيان رسمي أن نوري أُصيب باضطراب ضربات القلب خلال مباراة ودية أمام نادي فيردر بريمن الألماني. وأضاف أن فرص تعافي نوري من الإصابة معدومة. وأوضح البيان أن "التشخيص خلص إلى أن جزءا كبيرا من الدماغ توقف عن العمل. حدث كل هذا في الغالب بسبب نقص إمدادات الأكسجين في الدماغ.

منذ الحادث أصبح نوري غير قادر على تحريك عضلاته أوالتحدث أو الرؤية أو السماع أو الشعور، وهو يعيش حاليا في مستشفى في أمستردام في المركز الطبي الأكاديمي.

في 26 مارس 2020، أعلن عبد الرحيم شقيق اللاعب أنه استفاق من غيبوبته التي دامت حوالي 3 سنوات.

الإشادة والتقدير
منذ ظهوره في أكاديمية أياكس أمستردام كان عبد الحق نوري محط أنظار العديد من الأندية الرياضية واللاعبين الحاليين أو اللاعبين الأسطوريين السابقين والمدربين والصحافة بشكل عام باعتباره أحد أفضل المواهب الكروية الهولندية الصاعدة. وبالرغم من كونه لم تتح له الفرصة للعب موسم كامل مع فريق أياكس، إلا أن الكثيرون أدركوا أن مستقبل نوري كان سيكون حافلا لولا الإصابة، وهو ما عبر عنه العديد من المدربين المشهورين الذين التقوه أو قاموا بتدريبه.

غالبًا ما كانت وسائل الإعلام الهولندية تقارنه بالاعب الأسطوري يوهان كرويف، لكن نوري كان يرفض هذه المقارنة مصرحا : «"يجب ألا نجري هذه المقارنة أبدًا. لأن كرويف هو الأفضل في العالم".» كما صرح اللاعب الأرميني آراس أوزبيليز قائلا «"أستفيد بمجرد مشاهدة عبد الحق نوري يلعب".» فيما قال المدرب ديفيد إندت، الذي سيق له وأن درب نوري منذ بدايته في أكاديمية أياكس في أمستردام، «"يستمتع نوري كثيرا بالكرة، فهو يرقص معها وموهبته ملحوظة بسرعة في كل لقاء يجادل فيه. فأسلوبه وسيطرته ورؤيته للعبة، تجعلانه يجد دائماً الحل لكل شيء."»

Birds

Birds

Birds are a group of warm-blooded vertebrates constituting the class Aves, characterized by feathers, toothless beaked jaws, the laying of hard-shelled eggs, a high metabolic rate, a four-chambered heart, and a strong yet lightweight skeleton. Birds live worldwide and range in size from the 5 cm (2 in) bee hummingbird to the 2.75 m (9 ft) ostrich. There are about ten thousand living species,[3] more than half of which are passerine, or "perching" birds. Birds have wings whose development varies according to species; the only known groups without wings are the extinct moa and elephant birds. Wings, which evolved from forelimbs, gave birds the ability to fly, although further evolution has led to the loss of flight in some birds, including ratites, penguins, and diverse endemic island species. The digestive and respiratory systems of birds are also uniquely adapted for flight. Some bird species of aquatic environments, particularly seabirds and some waterbirds, have further evolved for swimming.

Birds are a group of feathered theropod dinosaurs, and constitute the only living dinosaurs. Likewise, the closest living relatives of birds are the crocodilians. Birds are descendants of the primitive avialans (whose members include Archaeopteryx) which first appeared about 160 million years ago (mya) in China. According to DNA evidence, modern birds (Neornithes) evolved in the Middle to Late Cretaceous, and diversified dramatically around the time of the Cretaceous–Paleogene extinction event 66 mya, which killed off the pterosaurs and all non-avian dinosaurs.

Many social species pass on knowledge across generations, which is considered a form of culture. Birds are social, communicating with visual signals, calls, and songs, and participating in such behaviours as cooperative breeding and hunting, flocking, and mobbing of predators. The vast majority of bird species are socially (but not necessarily sexually) monogamous, usually for one breeding season at a time, sometimes for years, but rarely for life. Other species have breeding systems that are polygynous (one male with many females) or, rarely, polyandrous (one female with many males). Birds produce offspring by laying eggs which are fertilised through sexual reproduction. They are usually laid in a nest and incubated by the parents. Most birds have an extended period of parental care after hatching.

Many species of birds are economically important as food for human consumption and raw material in manufacturing, with domesticated and undomesticated birds being important sources of eggs, meat, and feathers. Songbirds, parrots, and other species are popular as pets. Guano (bird excrement) is harvested for use as a fertiliser. Birds figure throughout human culture. About 120 to 130 species have become extinct due to human activity since the 17th century, and hundreds more before then. Human activity threatens about 1,200 bird species with extinction, though efforts are underway to protect them. Recreational birdwatching is an important part of the ecotourism industry.
The first classification of birds was developed by Francis Willughby and John Ray in their 1676 volume Ornithologiae.[4] Carl Linnaeus modified that work in 1758 to devise the taxonomic classification system currently in use.[5] Birds are categorised as the biological class Aves in Linnaean taxonomy. Phylogenetic taxonomy places Aves in the dinosaur clade Theropoda.[6]

Definition
Aves and a sister group, the order Crocodilia, contain the only living representatives of the reptile clade Archosauria. During the late 1990s, Aves was most commonly defined phylogenetically as all descendants of the most recent common ancestor of modern birds and Archaeopteryx lithographica.[7] However, an earlier definition proposed by Jacques Gauthier gained wide currency in the 21st century, and is used by many scientists including adherents of the Phylocode system. Gauthier defined Aves to include only the crown group of the set of modern birds. This was done by excluding most groups known only from fossils, and assigning them, instead, to the Avialae,[8] in part to avoid the uncertainties about the placement of Archaeopteryx in relation to animals traditionally thought of as theropod dinosaurs.

Gauthier[9] identified four different definitions for the same biological name "Aves", which is a problem. Gauthier proposed to reserve the term Aves only for the crown group consisting of the last common ancestor of all living birds and all of its descendants, which corresponds to meaning number 4 below. He assigned other names to the other groups.
Aves can mean all archosaurs closer to birds than to crocodiles (alternately Avemetatarsalia)
Aves can mean those advanced archosaurs with feathers (alternately Avifilopluma)
Aves can mean those feathered dinosaurs that fly (alternately Avialae)
Aves can mean the last common ancestor of all the currently living birds and all of its descendants (a "crown group", in this sense synonymous with Neornithes)
Under the fourth definition Archaeopteryx is an avialan, and not a member of Aves. Gauthier's proposals have been adopted by many researchers in the field of palaeontology and bird evolution, though the exact definitions applied have been inconsistent. Avialae, initially proposed to replace the traditional fossil content of Aves, is often used synonymously with the vernacular term "bird" by these researchers.[10]

Most researchers define Avialae as branch-based clade, though definitions vary. Many authors have used a definition similar to "all theropods closer to birds than to Deinonychus."[11][12] Avialae is also occasionally defined as an apomorphy-based clade (that is, one based on physical characteristics). Jacques Gauthier, who named Avialae in 1986, re-defined it in 2001 as all dinosaurs that possessed feathered wings used in flapping flight, and the birds that descended from them.[9][13]

Dinosaurs and the origin of birds
Based on fossil and biological evidence, most scientists accept that birds are a specialised subgroup of theropod dinosaurs,[16] and more specifically, they are members of Maniraptora, a group of theropods which includes dromaeosaurs and oviraptorids, among others.[17] As scientists have discovered more theropods closely related to birds, the previously clear distinction between non-birds and birds has become blurred. Recent discoveries in the Liaoning Province of northeast China, which demonstrate many small theropod feathered dinosaurs, contribute to this ambiguity.[18][19][20]

The consensus view in contemporary palaeontology is that the flying theropods, or avialans, are the closest relatives of the deinonychosaurs, which include dromaeosaurids and troodontids.[21] Together, these form a group called Paraves. Some basal members of this group, such as Microraptor, have features which may have enabled them to glide or fly. The most basal deinonychosaurs were very small. This evidence raises the possibility that the ancestor of all paravians may have been arboreal, have been able to glide, or both.[22][23] Unlike Archaeopteryx and the non-avialan feathered dinosaurs, who primarily ate meat, recent studies suggest that the first avialans were omnivores.[24]

The Late Jurassic Archaeopteryx is well known as one of the first transitional fossils to be found, and it provided support for the theory of evolution in the late 19th century. Archaeopteryx was the first fossil to display both clearly traditional reptilian characteristics—teeth, clawed fingers, and a long, lizard-like tail—as well as wings with flight feathers similar to those of modern birds. It is not considered a direct ancestor of birds, though it is possibly closely related to the true ancestor.[25]

Early evolution
The earliest known avialan fossils come from the Tiaojishan Formation of China, which has been dated to the late Jurassic period (Oxfordian stage), about 160 million years ago. The avialan species from this time period include Anchiornis huxleyi, Xiaotingia zhengi, and Aurornis xui.[10]

The well-known early avialan, Archaeopteryx, dates from slightly later Jurassic rocks (about 155 million years old) from Germany. Many of these early avialans shared unusual anatomical features that may be ancestral to modern birds, but were later lost during bird evolution. These features include enlarged claws on the second toe which may have been held clear of the ground in life, and long feathers or "hind wings" covering the hind limbs and feet, which may have been used in aerial maneuvering.[27]

Avialans diversified into a wide variety of forms during the Cretaceous Period.[28] Many groups retained primitive characteristics, such as clawed wings and teeth, though the latter were lost independently in a number of avialan groups, including modern birds (Aves). While the earliest forms, such as Archaeopteryx and Jeholornis, retained the long bony tails of their ancestors,[28] the tails of more advanced avialans were shortened with the advent of the pygostyle bone in the group Pygostylia. In the late Cretaceous, about 100 million years ago, the ancestors of all modern birds evolved a more open pelvis, allowing them to lay larger eggs compared to body size.[29] Around 95 million years ago, they evolved a better sense of smell.[30]

Early diversity of bird ancestors
The first large, diverse lineage of short-tailed avialans to evolve were the enantiornithes, or "opposite birds", so named because the construction of their shoulder bones was in reverse to that of modern birds. Enantiornithes occupied a wide array of ecological niches, from sand-probing shorebirds and fish-eaters to tree-dwelling forms and seed-eaters. While they were the dominant group of avialans during the Cretaceous period, enantiornithes became extinct along with many other dinosaur groups at the end of the Mesozoic era.[28]

Many species of the second major avialan lineage to diversify, the Euornithes (meaning "true birds", because they include the ancestors of modern birds), were semi-aquatic and specialised in eating fish and other small aquatic organisms. Unlike the enantiornithes, which dominated land-based and arboreal habitats, most early euornithes lacked perching adaptations and seem to have included shorebird-like species, waders, and swimming and diving species.

The latter included the superficially gull-like Ichthyornis[32] and the Hesperornithiformes, which became so well adapted to hunting fish in marine environments that they lost the ability to fly and became primarily aquatic.[28] The early euornithes also saw the development of many traits associated with modern birds, like strongly keeled breastbones, toothless, beaked portions of their jaws (though most non-avian euornithes retained teeth in other parts of the jaws).[33] Euornithes also included the first avialans to develop true pygostyle and a fully mobile fan of tail feathers,[34] which may have replaced the "hind wing" as the primary mode of aerial maneuverability and braking in flight.[27]

A study on mosaic evolution in the avian skull found that the last common ancestor of all neornithes might have had a beak similar to that of the modern hook-billed vanga and a skull similar to that of the Eurasian golden oriole. As both species are small aerial and canopy foraging omnivores, a similar ecological niche was inferred for this hypothetical ancestor.[35]

Diversification of modern birds

All modern birds lie within the crown group Aves (alternately Neornithes), which has two subdivisions: the Palaeognathae, which includes the flightless ratites (such as the ostriches) and the weak-flying tinamous, and the extremely diverse Neognathae, containing all other birds.[36] These two subdivisions are often given the rank of superorder,[37] although Livezey and Zusi assigned them "cohort" rank.[6] Depending on the taxonomic viewpoint, the number of known living bird species varies anywhere from 9,800[38] to 10,758.[39]

The discovery of Vegavis, a late Cretaceous member of the Anatidae, proved that the diversification of modern birds started before the Cenozoic era.[40] The affinities of an earlier fossil, the possible galliform Austinornis lentus, dated to about 85 million years ago,[41] are still too controversial to provide a fossil evidence of modern bird diversification.

Most studies agree on a Cretaceous age for the most recent common ancestor of modern birds but estimates range from the Middle Cretaceous[1] to the latest Late Cretaceous.[42] Similarly, there is no agreement on whether most of the early diversification of modern birds occurred before or after the Cretaceous–Palaeogene extinction event.[43] This disagreement is in part caused by a divergence in the evidence; most molecular dating studies suggests a Cretaceous evolutionary radiation, while fossil evidence points to a Cenozoic radiation (the so-called 'rocks' versus 'clocks' controversy). Previous attempts to reconcile molecular and fossil evidence have proved controversial,[43][44] but more recent estimates, using a more comprehensive sample of fossils and a new way of calibrating molecular clocks, showed that while modern birds originated early in the Late Cretaceous, a pulse of diversification in all major groups occurred around the Cretaceous–Palaeogene extinction event.[45]

Birds live and breed in most terrestrial habitats and on all seven continents, reaching their southern extreme in the snow petrel's breeding colonies up to 440 kilometres (270 mi) inland in Antarctica.[52] The highest bird diversity occurs in tropical regions. It was earlier thought that this high diversity was the result of higher speciation rates in the tropics; however recent studies found higher speciation rates in the high latitudes that were offset by greater extinction rates than in the tropics.[53] Many species migrate annually over great distances and across oceans; several families of birds have adapted to life both on the world's oceans and in them, and some seabird species come ashore only to breed,[54] while some penguins have been recorded diving up to 300 metres (980 ft) deep.[55]

Many bird species have established breeding populations in areas to which they have been introduced by humans. Some of these introductions have been deliberate; the ring-necked pheasant, for example, has been introduced around the world as a game bird.[56] Others have been accidental, such as the establishment of wild monk parakeets in several North American cities after their escape from captivity.[57] Some species, including cattle egret,[58] yellow-headed caracara[59] and galah,[60] have spread naturally far beyond their original ranges as agricultural practices created suitable new habitat.
Skeletal system
The skeleton consists of very lightweight bones. They have large air-filled cavities (called pneumatic cavities) which connect with the respiratory system.[61] The skull bones in adults are fused and do not show cranial sutures.[62] The orbits are large and separated by a bony septum. The spine has cervical, thoracic, lumbar and caudal regions with the number of cervical (neck) vertebrae highly variable and especially flexible, but movement is reduced in the anterior thoracic vertebrae and absent in the later vertebrae.[63] The last few are fused with the pelvis to form the synsacrum.[62] The ribs are flattened and the sternum is keeled for the attachment of flight muscles except in the flightless bird orders. The forelimbs are modified into wings.[64] The wings are more or less developed depending on the species; the only known groups that lost their wings are the extinct moa and elephant birds.[65]

Excretory system
Like the reptiles, birds are primarily uricotelic, that is, their kidneys extract nitrogenous waste from their bloodstream and excrete it as uric acid, instead of urea or ammonia, through the ureters into the intestine. Birds do not have a urinary bladder or external urethral opening and (with exception of the ostrich) uric acid is excreted along with faeces as a semisolid waste.[66][67][68] However, birds such as hummingbirds can be facultatively ammonotelic, excreting most of the nitrogenous wastes as ammonia.[69] They also excrete creatine, rather than creatinine like mammals.[62] This material, as well as the output of the intestines, emerges from the bird's cloaca.[70][71] The cloaca is a multi-purpose opening: waste is expelled through it, most birds mate by joining cloaca, and females lay eggs from it. In addition, many species of birds regurgitate pellets.[72]

Males within Palaeognathae (with the exception of the kiwis), the Anseriformes (with the exception of screamers), and in rudimentary forms in Galliformes (but fully developed in Cracidae) possess a penis, which is never present in Neoaves.[73][74] The length is thought to be related to sperm competition.[75] When not copulating, it is hidden within the proctodeum compartment within the cloaca, just inside the vent.

The digestive system of birds is unique, with a crop for storage and a gizzard that contains swallowed stones for grinding food to compensate for the lack of teeth.[76] Most birds are highly adapted for rapid digestion to aid with flight.[77] Some migratory birds have adapted to use protein stored in many parts of their bodies, including protein from the intestines, as additional energy during migration.[78]

Respiratory and circulatory systems
Birds have one of the most complex respiratory systems of all animal groups.[62] Upon inhalation, 75% of the fresh air bypasses the lungs and flows directly into a posterior air sac which extends from the lungs and connects with air spaces in the bones and fills them with air. The other 25% of the air goes directly into the lungs. When the bird exhales, the used air flows out of the lungs and the stored fresh air from the posterior air sac is simultaneously forced into the lungs. Thus, a bird's lungs receive a constant supply of fresh air during both inhalation and exhalation.[79] Sound production is achieved using the syrinx, a muscular chamber incorporating multiple tympanic membranes which diverges from the lower end of the trachea;[80] the trachea being elongated in some species, increasing the volume of vocalisations and the perception of the bird's size.[81]

In birds, the main arteries taking blood away from the heart originate from the right aortic arch (or pharyngeal arch), unlike in the mammals where the left aortic arch forms this part of the aorta.[62] The postcava receives blood from the limbs via the renal portal system. Unlike in mammals, the circulating red blood cells in birds retain their nucleus.[82]

Heart type and features
The avian circulatory system is driven by a four-chambered, myogenic heart contained in a fibrous pericardial sac. This pericardial sac is filled with a serous fluid for lubrication.[83] The heart itself is divided into a right and left half, each with an atrium and ventricle. The atrium and ventricles of each side are separated by atrioventricular valves which prevent back flow from one chamber to the next during contraction. Being myogenic, the heart's pace is maintained by pacemaker cells found in the sinoatrial node, located on the right atrium.

The sinoatrial node uses calcium to cause a depolarising signal transduction pathway from the atrium through right and left atrioventricular bundle which communicates contraction to the ventricles. The avian heart also consists of muscular arches that are made up of thick bundles of muscular layers. Much like a mammalian heart, the avian heart is composed of endocardial, myocardial and epicardial layers.[83] The atrium walls tend to be thinner than the ventricle walls, due to the intense ventricular contraction used to pump oxygenated blood throughout the body. Avian hearts are generally larger than mammalian hearts when compared to body mass. This adaptation allows more blood to be pumped to meet the high metabolic need associated with flight.[84]

Organisation
Birds have a very efficient system for diffusing oxygen into the blood; birds have a ten times greater surface area to gas exchange volume than mammals. As a result, birds have more blood in their capillaries per unit of volume of lung than a mammal.[84] The arteries are composed of thick elastic muscles to withstand the pressure of the ventricular contractions, and become more rigid as they move away from the heart. Blood moves through the arteries, which undergo vasoconstriction, and into arterioles which act as a transportation system to distribute primarily oxygen as well as nutrients to all tissues of the body.[85] As the arterioles move away from the heart and into individual organs and tissues they are further divided to increase surface area and slow blood flow. Blood travels through the arterioles and moves into the capillaries where gas exchange can occur.

Capillaries are organized into capillary beds in tissues; it is here that blood exchanges oxygen for carbon dioxide waste. In the capillary beds, blood flow is slowed to allow maximum diffusion of oxygen into the tissues. Once the blood has become deoxygenated, it travels through venules then veins and back to the heart. Veins, unlike arteries, are thin and rigid as they do not need to withstand extreme pressure. As blood travels through the venules to the veins a funneling occurs called vasodilation bringing blood back to the heart.[85] Once the blood reaches the heart, it moves first into the right atrium, then the right ventricle to be pumped through the lungs for further gas exchange of carbon dioxide waste for oxygen. Oxygenated blood then flows from the lungs through the left atrium to the left ventricle where it is pumped out to the body.

Fox

Fox

The Fox Broadcasting Company[1] (often shortened to Fox and stylized in all caps as FOX)[2] is an American broadcast television network that is a flagship property of the Fox Corporation. The network is headquartered at 1211 Avenue of the Americas in New York City, with additional offices at the Fox Broadcasting Center (also in New York) and at the Fox Television Center in Los Angeles.

Launched on October 9, 1986, as a competitor to the Big Three television networks (ABC, CBS and NBC), Fox went on to become the most successful attempt at a fourth television network. It was the highest-rated network in the 18–49 demographic from 2004 to 2012, and earned the position as the most-watched American television network in total viewership during the 2007–08 season.[3][4]

Fox and its affiliated companies operate many entertainment channels in international markets, although these do not necessarily air the same programming as the U.S. network. Most viewers in Canada have access to at least one U.S.-based Fox affiliate, either free-to-air or through a pay television provider, although Fox's National Football League broadcasts and most of its prime time programming are subject to simultaneous substitution regulations for pay television providers imposed by the Canadian Radio-television and Telecommunications Commission (CRTC) to protect rights held by domestically based networks.

Fox is named after what was then called 20th Century Fox, its original corporate sibling, and indirectly for producer William Fox, who founded one of the movie studio's predecessors, Fox Film. Fox is a member of the North American Broadcasters Association and the National Association of Broadcasters.
History
Origins
20th Century Fox had been involved in television production as early as the 1950s, producing several syndicated programs.[5] Following the demise of the DuMont Television Network in August 1956, after it became mired in severe financial problems, the NTA Film Network was launched as a new "fourth network".[6] 20th Century Fox would also produce original content for the NTA network.[5] The film network effort would fail after a few years, but 20th Century Fox continued to dabble in television through its production arm, TCF Television Productions, producing series (such as Perry Mason) for the three major broadcast television networks (ABC, NBC, and CBS).

1980s: Establishment of the network
Foundations
The Fox network's foundations were laid in March 1985 through News Corporation's $255 million purchase of a 50% interest in TCF Holdings, the parent company of the 20th Century Fox film studio. In May 1985, News Corporation, a media company owned by Australian publishing magnate Rupert Murdoch that had mainly served as a newspaper publisher at the time of the TCF Holdings deal, agreed to pay $2.55 billion to acquire independent television stations in six major U.S. cities from the John Kluge-run broadcasting company Metromedia: WNEW-TV in New York City, WTTG in Washington, D.C., KTTV in Los Angeles, KRIV-TV in Houston, WFLD-TV in Chicago, and KRLD-TV in Dallas. A seventh station, ABC affiliate WCVB-TV in Boston, was part of the original transaction but was spun off to the Hearst Broadcasting subsidiary of the Hearst Corporation in a separate, concurrent deal as part of a right of first refusal related to that station's 1982 sale to Metromedia.[7][8][9] (Two years later, News Corporation acquired WXNE-TV in that market from the Christian Broadcasting Network and changed its call letters to WFXT.)

Because Metromedia (originally known as Metropolitan Broadcasting at its founding) was spun off from the failed DuMont Television Network, radio personality Clarke Ingram has suggested that the Fox network is a revival or at least a linear descendant of DuMont.[10] The former Metromedia stations WNEW (originally known as WABD) and WTTG were two of the three original owned-and-operated stations of the DuMont network, and that the former base of DuMont's operations, the DuMont Tele-Centre in Manhattan, eventually became the present-day Fox Television Center.

Beginning of the network
In October 1985, 20th Century Fox announced its intentions to form a fourth television network that would compete with ABC, CBS, and NBC. The plans were to use the combination of the Fox studios and the former Metromedia stations to both produce and distribute programming. Organizational plans for the network were held off until the Metromedia acquisitions cleared regulatory hurdles. Then, in December 1985, Rupert Murdoch agreed to pay $325 million to acquire the remaining equity in TCF Holdings from his original partner, Marvin Davis. The purchase of the Metromedia stations was approved by the Federal Communications Commission (FCC) in March 1986; the call letters of the New York City and Dallas outlets were subsequently changed respectively to WNYW and KDAF.[11] These first six stations, then broadcasting to a combined reach of 22% of the nation's households, became known as the Fox Television Stations group. With the sole exception of KDAF (which was sold to Renaissance Broadcasting in 1995, at which time it became a charter affiliate of The WB), all of the original owned-and-operated stations ("O&Os") are still part of the Fox network today. Like the core O&O group, Fox's affiliate body initially consisted of independent stations (a few of which had maintained affiliations with ABC, NBC, CBS, or DuMont earlier in their existences). The local charter affiliate was, in most cases, that market's top-rated independent, however, Fox opted to affiliate with a second-tier independent station in markets where a more established independent declined the affiliation (such as Denver, Phoenix and St. Louis). Largely because of both these factors, Fox in a situation very similar to what DuMont had experienced four decades before had little choice but to affiliate with UHF stations in all except a few (mainly larger) markets where the network gained clearance.[12]

The Fox Broadcasting Company officially debuted with a soft launch at 11:00 p.m. Eastern and Pacific Time on Thursday, October 9, 1986. Its inaugural program was a late-night talk show, The Late Show, which was hosted by comedian Joan Rivers.[13][14] After a strong start, The Late Show quickly eroded in the ratings, it was never able to overtake NBC stalwart The Tonight Show whose then-host Johnny Carson, upset over her becoming his late-night competitor, banned Rivers (a frequent Tonight guest and substitute host) from appearing on his show (Rivers would not appear on Tonight again until February 2014, seven months before her death, by which time Jimmy Fallon was its host). By early 1987, Rivers (and her then-husband Edgar Rosenberg, the show's original executive producer) quit The Late Show after disagreements with the network over the show's creative direction, the program then began to be hosted by a succession of guest hosts. After that point, some stations that affiliated with Fox in the weeks before the April 1987 launch of its prime time lineup (such as WCGV-TV in Milwaukee and WDRB-TV in Louisville) signed affiliation agreements with the network on the condition that they would not have to carry The Late Show due to the program's weak ratings.

The network had its "grand opening" when it expanded its programming into prime time on April 5, 1987, inaugurating its Sunday night lineup with the premieres of the sitcom Married... with Children and the sketch comedy series The Tracey Ullman Show. The premieres of both series were rebroadcast twice following their initial airings (at 7:00 p.m. and 7:30 p.m. Eastern/Pacific, respectively) that night, which Jamie Kellner, who served as the network's President and Chief Operating Officer until his resignation in January 1993, stated would allow viewers to "sample FBC programming without missing 60 Minutes, Murder, She Wrote, or the 8 o'clock movies".[15][16][17] Fox added one new show per week over the next several weeks, with the drama 21 Jump Street and comedies Mr. President and Duet completing its Sunday schedule.[18] On July 11, 1987, the network rolled out its Saturday night schedule with the premiere of the supernatural drama series Werewolf, which began with a two-hour pilot movie event. Three other series were added to the Saturday lineup over the next three weeks: comedies The New Adventures of Beans Baxter, Karen's Song, and Down and Out in Beverly Hills (the latter being an adaptation of the film of the same name). Both Karen's Song and Down and Out in Beverly Hills were canceled by the start of the 1987–88 television season, the network's first fall launch, and were replaced by the sitcoms Second Chance and Women in Prison.

In regards to its late night lineup, Fox had already decided to cancel The Late Show, and had a replacement series in development, The Wilton North Report, when the former series began a ratings resurgence under its final guest host, comedian Arsenio Hall. Wilton North lasted just a few weeks, however, and the network was unable to reach a deal with Hall to return as host when it hurriedly revived The Late Show in early 1988. The Late Show went back to featuring guest hosts, eventually selecting Ross Shafer as its permanent host, only for it to be canceled for good by October 1988, while Hall signed a deal with Paramount Television to develop his own syndicated late night talk show, The Arsenio Hall Show. Fox aired the 39th Primetime Emmy Awards and would air the next five editions.

Although the network had modest successes in Married... with Children and The Tracy Ullman Show, several affiliates were disappointed with Fox's largely underperforming programming lineup during the network's first three years, KMSP-TV in Minneapolis and KPTV in Portland, Oregon, both owned at the time by Chris-Craft Television, disaffiliated from Fox in 1988 (with KITN, now WFTC) and KPDX respectively replacing those stations as Fox affiliates), citing that the network's weaker program offerings were hampering viewership of their stronger syndicated slate.

At the start of the 1989–90 television season, Fox added a third night of programming, on Mondays. The season heralded the start of a turnaround for Fox. It saw the debut of a midseason replacement series, The Simpsons, an animated series that originated as a series of shorts on The Tracey Ullman Show, ranked at a three-way tie for 29th place in the Nielsen ratings, it became a breakout hit and was the first Fox series to break the Top 30. The Simpsons, at 30 years as of 2018, is the longest-running American sitcom, the longest-running American animated program, and in 2009, it surpassed Gunsmoke as the longest-running American scripted primetime television series. That year, Fox also first introduced the documentary series Cops and crime-focused magazine program America's Most Wanted (the latter of which debuted as a half-hour series as part of the network's mainly comedy-based Sunday lineup for its first season, before expanding to an hour and moving to Fridays for the 1990–91 season). These two series, which would become staples on the network for just over two decades, would eventually be paired to form the nucleus of Fox's Saturday night schedule beginning in the 1994–95 season. Meanwhile, Married... with Children which broke ground from other family sitcoms of the period as it centered on a dysfunctional lower-middle-class family, whose patriarch often openly loathed his failures and being saddled with a wife and two children saw viewer interest substantially increase beginning in its third season after, in an ironic twist, Michigan homemaker Terry Rakolta lodged a boycott to force Fox to cancel the series after objecting to risque humor and sexual content featured in a 1989 episode. Married...'s newfound success led it to become the network's longest-running live-action sitcom, airing for 11 seasons.

1990s: Rise into mainstream success and beginnings of rivalry with the Big Three
Fox survived where DuMont and other attempts to start a fourth network had failed because it programmed just under the number of hours defined by the FCC to legally be considered a network. This allowed Fox to make revenue in ways forbidden to the established networks (for instance, it did not have to adhere to the Financial Interest and Syndication Rules that were in effect at the time), since during its first years it was considered to be merely a large group of stations. By comparison, DuMont had been saddled by numerous regulatory barriers that hampered its potential to grow, most notably a ban on acquiring additional stations, during an era when the FCC had much tighter ownership limits for television stations (limiting broadcasters to a maximum of five stations nationwide) than it did when Fox launched. In addition, Murdoch was more than willing to open his wallet to get and keep programming and talent. DuMont, in contrast, operated on a shoestring budget and was unable to keep the programs and stars it had.[19]

Most of the other startup networks that launched in later years (such as The WB, UPN and The CW) followed Fox's model as well. Furthermore, DuMont operated during a time when the FCC did not require television manufacturers to include UHF capability.[20] In order to see DuMont's UHF stations, most people had to buy an expensive converter. Even then, the picture quality was marginal at best.[citation needed] By the time Fox launched, cable allowed UHF stations to generally be on an equal footing with VHF stations.[12]

Although Fox was growing rapidly as a network and had established itself as a presence, it was still not considered a major competitor to the established "Big Three" broadcast networks, ABC, CBS, and NBC. From its launch, Fox had the advantage of offering programs intended to appeal toward a younger demographic adults between 18 and 49 years of age – and that were edgier in content, whereas some programs that were carried by the "Big Three" networks attracted an older-skewing audience. Until the early 1990s, when Fox expanded its programming to additional nights and outside prime time, most Fox stations were still essentially formatted as independent stations – filling their schedules with mainly first-run and acquired programming, and, during prime time, running either syndicated programs or, more commonly, movies on nights when the network did not provide programming. Few Fox stations carried local newscasts during the network's early years, unlike the owned-and-operated stations and affiliates of its established rivals. Those that did were mostly based in larger markets (including some of the network's O&Os) and retained newscasts that had aired for decades. Even then, these news operations were limited to one newscast per day, following the network's prime time lineup.

On September 6, 1990, Fox reached an agreement with TCI (the nation's largest cable company at the time) in which TCI systems in markets that were not served by an over-the-air Fox affiliate at the time would become charter affiliates of a cable-only national feed of the network known as Foxnet.[21][22] The cable-only network launched on June 6, 1991, bringing Fox programming to smaller markets that did not carry a default Fox affiliate at the time; it would manage to reach a total of 1.3 million subscribers by 1992.[23][24]

As Fox gradually headed towards carrying a full week's worth of programming in prime time through the addition of programming on Thursday and Friday nights at the start of the 1990–91 season the network's added offerings included the scheduling of The Simpsons opposite veteran NBC sitcom The Cosby Show as part of Fox's initial Thursday night lineup that fall (along with future hit Beverly Hills, 90210, which would become the network's longest-running drama, airing for ten seasons) after only a half-season of success on Sunday nights. The show performed well in its new Thursday slot, spending four seasons there and helping to launch Martin, another Fox comedy that became a hit when it debuted in August 1992. The Simpsons returned to Sunday nights in the fall of 1994, and has remained there ever since.

The sketch comedy series In Living Color, which debuted in April 1990, created many memorable characters and launched the careers of future movie stars Jim Carrey, Jamie Foxx, Damon Wayans, Keenen Ivory Wayans and Jennifer Lopez (the latter of whom was a member of the show's dance troupe, the "Fly Girls"). The series also gained international prominence after Fox aired a special live episode in January 1992 as an alternative to the halftime show during Super Bowl XXVI, which was broadcast on CBS, marking the start of Fox's rivalry with the "Big Three" networks while popularizing the counterprogramming strategy against the Super Bowl telecast.

The early and mid-1990s saw the debuts of several soap opera-style prime time dramas aimed at younger audiences that became quick hits, which, in addition to Beverly Hills, 90210, included its adult-focused spin-off Melrose Place (which initially had a mediocre ratings performance, before viewership rose significantly midway through its first season following Heather Locklear's addition to the cast) and family drama Party of Five. The early and mid-1990s also saw the network launch several series aimed at a black audience, which, in addition to Martin, included the sitcom Living Single and police procedural New York Undercover.[25]

Luring the NFL and affiliation switches
Despite having a few successful shows like the science fiction drama The X-Files, Fox still lacked credibility among viewers.[26] Even those working in television thought of the network as "the one that has that cartoon show" (The Simpsons). More than 85% of affiliates in 1993 were UHF stations. Fox become a viable competitor to the older networks when it won broadcast television rights to the National Football League away from CBS. In December 1993, Fox signed a contract with the NFL to televise games from the National Football Conference—which had been airing its games on CBS since 1956—starting with the 1994 season. The initial four-year contract, which Fox bid $1.58 billion to obtain—while CBS offered $295 million per year to retain the rights[27]—also included the exclusive U.S. television rights to Super Bowl XXXI in 1997.[28] The network also lured Pat Summerall, John Madden, Dick Stockton, Matt Millen, James Brown, Terry Bradshaw, and behind-the-scenes production personnel, from CBS Sports to staff its NFL coverage.[27]

Shortly afterward, News Corporation began striking affiliation deals with, and later purchasing, more television station groups. On May 23, 1994, Fox agreed to purchase a 20% stake in New World Communications, a television and film production company controlled by investor Ronald Perelman that had just recently entered into broadcasting through its 1993 purchase of seven stations owned by SCI Television. As a result of Fox acquiring a 20% minority interest in the company, New World signed an agreement to switch the affiliations of twelve stations (eight CBS affiliates, three ABC affiliates two of which were subsequently placed in a blind trust and then sold directly to Fox due to conflicts with FCC ownership rules and one NBC affiliate) that it had either already owned outright or was in the process of acquiring from Citicasters and Argyle Communications at the time to Fox starting in September 1994 and continuing as existing affiliation contracts with their existing major network partners expired.[29][30][31]

That summer, SF Broadcasting, a joint venture between Fox and Savoy Pictures that was founded in March 1994, purchased four stations from Burnham Broadcasting (three NBC affiliates and one ABC affiliate);[32][33] through a separate agreement, those stations would also switch to Fox between September 1995 and January 1996 as existing affiliation agreements lapsed. These two deals were not the first instances in which a longtime "Big Three" station affiliated with Fox: the network scored its first major coup when it moved its Miami affiliation from charter affiliate WCIX (which became a CBS owned-and-operated station, now WFOR-TV) to NBC affiliate WSVN in January 1989, the result of a three-station affiliation swap spurred by NBC's purchase of longtime CBS affiliate WTVJ. Through the expansion of its news programming and a refocused emphasis on crime stories and sensationalistic reporting under news director Joel Cheatwood, that switch helped the perennial third-place WSVN become a strong competitor in the Miami market.

The NFC contract, in fact, was the impetus for the affiliation deal with New World[29] and SF Broadcasting's purchase of the Burnham stations, as Fox sought to improve local coverage of its new NFL package by aligning the network with stations that had more established histories and advertiser value than its charter affiliates. The deals spurred a series of affiliation realignments between all four U.S. television networks involving individual stations and various broadcasting groups such as those between CBS and Group W (whose corporate parent later bought the network in August 1995), and ABC and the E. W. Scripps Company (which owned three Fox affiliates that switched to either ABC or NBC as a result of the New World deal) affecting 30 television markets between September 1994 and September 1996. The two deals also had the side benefit of increasing local news programming on the new Fox affiliates, mirroring the programming format adopted by WSVN upon that station's switch to the network (as well as expanding the number of news-producing stations in Fox's portfolio beyond mainly charter stations in certain large and mid-sized markets).

With significant market share for the first time ever and the rights to the NFL, Fox firmly established itself as the nation's fourth major network. Fox Television Stations would acquire New World outright on July 17, 1996 in a $2.48 billion stock purchase, making the latter's twelve Fox affiliates owned-and-operated stations of the network;[34][35] the deal was completed on January 22, 1997. Later, in August 2000, Fox bought several stations owned by Chris-Craft Industries and its subsidiaries BHC Communications and United Television for $5.5 billion (most of these stations were UPN affiliates, although its Minneapolis station KMSP-TV would rejoin Fox in September 2002 as an owned-and-operated station).[36] These purchases, for a time, made Fox Television Stations the largest owner of television stations in the U.S. (a title that has since been assumed by the Sinclair Broadcast Group, one of the network's largest affiliate groups).

Evolving programming
Fox completed its prime time expansion to all seven nights on January 19, 1993, with the launch of two additional nights of programming on Tuesdays and Wednesdays (The method of gradually adding nights to the programming schedule that began with the network's April 1987 prime time launch was replicated by The WB and UPN when those networks debuted in January 1995). September 1993 saw the heavy promotion and debut of a short-lived western series that incorporated science-fiction elements, The Adventures of Brisco County, Jr. However, it was the supernatural investigative drama that debuted immediately following it on Friday nights, The X-Files, that would find long-lasting success, and would become Fox's first series to crack Nielsen's year-end Top 20 most-watched network programs. After several other failed attempts at late night programming following the cancellation of The Late Show (most notably, the quick failure of The Chevy Chase Show in 1993), Fox finally found success in that time period with the debut of MADtv on October 14, 1995; the sketch comedy series became a solid competitor to NBC's Saturday Night Live for over a decade and was the network's most successful late night program as well as one of its most successful Saturday night shows, running for 14 seasons until 2009.

An attempt to make a larger effort to program Saturday nights by moving Married... with Children from its longtime Sunday slot and adding a new but short-lived sitcom (Love and Marriage) to the night at the beginning of the 1996–97 season backfired with the public, as it resulted in a brief cancellation of America's Most Wanted that was criticized by law enforcement and public officials, and was roundly rejected by viewers, which brought swift cancellation to the newer series.[37] Married... quickly returned to Sundays (before moving again to Mondays two months later); both it and Martin would end their runs at the end of that season. The Saturday schedule was revised in November 1996, to feature one new and one encore episode of Cops, and the revived America's Most Wanted: America Fights Back. Cops and AMW remained the anchors of Fox's Saturday lineup, making it the most stable night in American broadcast television for over 14 years; both shows eventually were among the few first-run programs remaining on Saturday evenings across the four major networks after decreasing prime time viewership – as more people opted to engage in leisure activities away from home rather than watch television on that night of the week led ABC, NBC and CBS to largely abandon first-run series on Saturdays (outside newsmagazines, sports and burned off prime time shows that failed on other nights) in favor of reruns and movies by the mid-2000s. America's Most Wanted ended its 22-year run on Fox in June 2011, and was subsequently picked up by Lifetime (before being cancelled for good in 2013);[38] Cops, in turn, would move its first-run episodes to Spike in 2013 after 23 seasons (ending its original run on Fox as the network's longest-running prime time program), leaving sports and repeats of reality and drama series as the only programs airing on Fox on Saturday evenings.[39]

By the 1997–98 season, Fox had three shows in the Nielsen Top 20, The X-Files (which ranked 11th), King of the Hill (which ranked 15th) and The Simpsons (which ranked 18th). Building around its flagship animated comedy The Simpsons, Fox would experience relative success with animated series in prime time, beginning with the debut of the Mike Judge-produced King of the Hill in 1997. Family Guy (the first of three adult-oriented animated series from Seth MacFarlane to air on the network) and Futurama (from Simpsons creator Matt Groening) would make their debuts in 1999, however, they were canceled in 2002 and 2003 respectively. Due to strong DVD sales and highly rated cable reruns on Cartoon Network's Adult Swim, Fox later decided to order new episodes of Family Guy, which began airing in 2005. Futurama would be revived with four direct-to-DVD films between 2007 and 2009 and would return as a first-run series on Comedy Central, where it ran from 2010 to 2013. Less successful efforts included The Critic, starring Saturday Night Live alumnus Jon Lovitz (which Fox picked up in 1994 after it was cancelled by ABC, only for the series to be cancelled again after its second season), and The PJs (which moved to The WB in 2000, after Fox cancelled that series after its second season). Other notable shows that debuted in the late 1990s included the quirky David E. Kelley-produced live-action dramedy Ally McBeal, the short-lived game show Greed, and the period comedy That '70s Show, the latter of which became Fox's second-longest-running live-action sitcom, airing for eight seasons.

Throughout the 1990s and into the next decade, Fox launched a slate of cable channels beginning with the 1994 debuts of general entertainment network FX and movie channel FXM: Movies from Fox (now FX Movie Channel), followed by the debut of Fox News Channel in August 1996. Its sports operations expanded with the acquisition of controlling interests in several regional sports networks (including the Prime Network and SportsChannel) between 1996 and 2000 to form Fox Sports Net (which launched in November 1996), its 2000 purchase of Speedvision (later Speed Channel, which was replaced in the United States by Fox Sports 1 in August 2013, however, it continues to exist in other North American and Caribbean countries as Fox Sports Racing), and the launches of Fox Sports World (later Fox Soccer, which was replaced by FXX in September 2013) and Fox Sports en Español (now Fox Deportes) in the early 2000s.

2000s: Rise to ratings leadership, the American Idol effect, and fierce rivalry with CBS
By 2000, many staple Fox shows of the 1990s had ended their runs. During the late 1990s and carrying over into the early 2000s, Fox put much of its efforts into producing reality shows many of which were considered to be sensationalistic and controversial in nature – such as Who Wants to Marry a Multi-Millionaire?, Temptation Island, Married by America, and Joe Millionaire (which became the first Fox program ever to crack the Nielsen Top 10), as well as video clip shows such as World's Wildest Police Videos and When Animals Attack!. After shedding most of these programs, Fox gradually filled its lineup with acclaimed dramas such as 24, The O.C., House, and Bones, and comedies such as The Bernie Mac Show, Malcolm in the Middle, and Arrested Development.

As the decade wore on, Fox began surpassing ABC and NBC in the ratings first in age demographics, then in overall viewership and placed second behind a resurgent CBS in total viewership beginning in 2002. Fox hit a major milestone in 2005 when it emerged as the most-watched U.S. broadcast network in the lucrative 18–49 demographic for the first time, largely boosted by the strength of the reality singing competition series American Idol. Regarded as the single most dominant program on 21st-century U.S. television, as well as the first Fox show to lead the Nielsen seasonal ratings, Idol had peak audiences of up to 38 million viewers during the 2003 season finale and double-season average audiences of around 31 million viewers in 2006 and 2007. Subsequently, it leapfrogged over Fox's Big Three competition to become the highest-rated U.S. television program overall starting with the 2003–04 season, becoming the first reality singing competition series in the country ever to reach first place in the seasonal ratings.

Idol remains the most recent U.S. television program to date to lead the national prime time ratings and attract at least 30 million viewers for at least two television seasons. It became as the most watched program on U.S. television by seasonal average viewership in the 2000s decade, as well as the most recent program scheduled to have successfully established a graveyard slot on U.S. television since the end of NBC's Friends in 2004 and the subsequent decline of the network's previously dominant "Must See TV" Thursday timeblock. By 2005, reality television succeeded sitcoms as the most popular form of entertainment in the U.S. as a result of Fox's rise with Idol and NBC's network declines. House, which aired as Idol's lead-out program on Tuesday nights, earned international prominence in the 21st century and became Fox's first prime time drama series (and the network's third program overall) to reach the Nielsen Top 10 beginning 2006.

Beginning 2004, CBS and Fox, which ranked as the two most-watched broadcast networks in the U.S. during the 2000s, have tended to equal one another in demographic ratings among general viewership, with both networks winning certain demographics by narrow margins; however, while Fox has the youngest-skewing viewer base, CBS is consistently regarded to have the oldest audience demographics among the major broadcast networks. Fox hit a milestone in February 2005 by scoring its first-ever sweeps victory in total viewership and demographic ratings, boosted largely by its broadcast of Super Bowl XXXIX and the strengths of American Idol, 24, House, and The O.C.

In September 2006, as a result of the increasing number of over-the-air Fox affiliates and the increased availability of digital subchannels carrying Fox in certain markets, Foxnet was discontinued.

A sweeping milestone came by the conclusion of the 2007–08 season on May 21, 2008, shortly after the widely acclaimed seventh-season finale of American Idol, when Fox outranked longtime leader CBS as the most watched television network in the United States overall for the first time, attributed to the strengths of Super Bowl XLII and its NFL game coverages, Idol and House during that season. Fox is currently the only non-Big Three network to earn first place overall since the start of Nielsen ratings in the 1950–51 season.[3]

In the late 2000s, Fox launched a few series that proved to be powerful hits in different respects. In 2007, the network began production on the game shows Are You Smarter Than a 5th Grader? and Don't Forget the Lyrics; both shows ran for a total of three seasons each, making them the longest-running game shows in Fox's history. In 2008, the supernatural mystery series Fringe debuted to moderate ratings but earned critical acclaim during its first season on Tuesdays. Throughout its run, the series developed a large loyal fanbase that turned the show into a cult favorite. In 2009, Glee premiered to average ratings when its pilot aired as a lead-out program of the eighth-season finale of American Idol, but earned positive reviews from critics. The show's viewership rose in the first two seasons, and attracted media attention that it formed a large, loyal international fanbase. The cast of the series has been acknowledged by notable luminaries such as the President of the United States Barack Obama and Oprah Winfrey, who have each asked the cast to perform live for various national events.

2010–2018: Network's ratings collapse and revamp in network programming
At the dawn of the 2010s, new comedies Raising Hope and New Girl gave Fox its first live-action comedy successes in years. The second season of Glee delivered that series' highest ratings during the 2010–11 season, with viewership peaking during its Super Bowl lead-out episode in February 2011. At the same time, Fox's live telecast of the Super Bowl XLV helped the network emerge as the first U.S. television network to earn an average single-night prime time audience of at least 100 million viewers.[40]

American Idol lost its first place standing among all network prime time programs during the 2011–12 finale (falling to second that season behind NBC Sunday Night Football), ending the longest streak at #1 for a prime time broadcast network series in U.S. television history, through its eight-year ratings domination in both the Adults 18–49 demographic and total viewership. Idol also remained in the Nielsen Top 10 for eleven years from 2003 to 2013, and became the highest-rated non-sports prime time television program as well as the highest-rated reality series in the U.S. from 2003 to 2012; these records marked the longest Nielsen ratings streaks of any Fox program in these categories. The 2012 season finale of American Idol marked the end of the season-long 25th anniversary of the establishment of Fox network, helping it win in the 18–49 demographic for the eighth consecutive season, the longest such streak according to Nielsen measurement records.

Fox suffered a collapse in viewership during the 2012–13 season; American Idol and Glee suffered steep ratings declines, while the network as a whole fell to third place (suffering an overall decrease by 22%) in total viewership and to second place in the 18–49 demographic (where it remained as of 2014) by the end of the season.

The decline in ratings continued into the 2013–14 season, with Fox placing fourth among the major networks in total viewership for the first time since 2001. Subsequently, on January 13, 2014, Fox announced that it would abandon its use of the standard concept of greenlighting shows through the initial order of pilot episodes during the designated "pilot season" (running from January through April), instead opting to pick up shows directly to series.[41]

Fox scored renewed ratings successes with its February 2014 live telecast of Super Bowl XLVIII, which became the second most watched television broadcast (by average) in U.S. history, and the lead-out programs that followed this event – New Girl and Brooklyn Nine-Nine. Later, in May 2014, Kevin Reilly announced that he would resign as chairman of Fox Entertainment.[42] On July 15, 2014, corporate parent 21st Century Fox announced that it would merge the operations of the network and 20th Century Fox Television into the newly created Fox Television Group, with 20th Century Fox Television co-chairpersons Dana Walden and Gary Newman appointed to head the division.[43]

The 2014–15 season saw hits in the freshmen dramas Gotham (based on the Batman mythos) and the Lee Daniels-produced Empire. Ratings for Empire, in particular, increased week-to-week throughout its first season, becoming the network's first successful American Idol lead-out since House, as well as the first American television program to consistently increase its episode-to-episode viewership during its first five weeks since the 1992 feat set by ABC's Roseanne. Empire ended its inaugural season as the first U.S. television show ever to increase its episodic viewership on a consistent basis throughout the course of a single season, as well as Fox's fourth program overall (and the first since the 2013 finale of American Idol) to enter the Nielsen Top 10 by the end of the 2014–15 season.[44][45][46]

The 2015–16 season marked a notable turnaround for Fox, as it jumps ahead of ABC to third place in nationwide ratings (both in overall viewership and in the 18–49 demo) and posted several firsts for the network and on U.S. television. Its improvement was boosted by the transfer of the Miss Universe and Miss USA pageants from NBC, as well as shows such as Grease: Live, Empire and the return of The X-Files after its most recent season ending in 2002. Grease: Live became the first live American TV musical special of the 21st century to be broadcast in front of a live studio audience (as well as the first ever live musical special aired by a non-Big Three network on primetime), while Empire and The X-Files ranked in the Nielsen Top 10 for the season, the first season with 2 Fox programs entering the top rankings since the American Idol-House duo of the 2007–2008 season (and the first ever season that Fox achieved such rankings without American Idol or any other reality television show from Fox in the Top 10).

2016 also marked the finale of American Idol in its original run on Fox after airing for fifteen seasons, ending an era of one of the most successful shows in U.S. television history. In February 2017, Fox broadcast Super Bowl LI, which also featured the first ever overtime in Super Bowl history. The broadcast attracted a U.S-all-time high total of 172 million viewers on peak conclusion, marking the first time that any U.S. television broadcast exceeded the 170-million viewership mark.[47]

2018–present: "New Fox" and sale of movie studio to Disney
On July 27, 2018, in a deal first announced December 2017, and completed March 20, 2019,[48] 21st Century Fox shareholders agreed to sell most of its key assets (including 20th Century Fox - now 20th Century Studios, 20th Television, and FX Networks) to The Walt Disney Company for $71.3 billion, following the spin-off of certain businesses. The sale did not include the Fox Broadcasting Company and television stations or the Fox Sports, Fox News, and Fox Business cable channels, which were to be maintained under a company tentatively referred to as "New Fox".[49][50] Because Disney already owns the American Broadcasting Company (ABC), the acquisition of the Fox network by Disney would have been unlawful under the Federal Communications Commission (FCC)'s rules prohibiting a merger between any of the four major broadcast networks.[51] As a result of the Disney/Fox deal, and with the merger of CBS and Viacom on December 4, 2019, Fox has become the only major U.S. broadcast network without attachment to any film studio.

It was acknowledged that Fox had placed a larger emphasis on its sports programming in its first upfronts since the deal was announced, including the acquisitions of the NFL's Thursday Night Football package and rights to the FIFA World Cup. It was also noted that Fox had been increasingly pivoting towards programs that could generate large audiences, as opposed to ones that become successful primarily through critical acclaim. On June 27, 2018, WWE announced that SmackDown would move to Fox and return to airing on Friday nights beginning October 4, 2019, following its run on USA Network, under a five-year contract valued at $205 million per-year.[52][53][54][55][56] The network also began to increase its non-scripted output, announcing the new celebrity music competition series The Masked Singer (based on the South Korean format King of Mask Singer), and the new game shows Mental Samurai and Spin the Wheel for the 2018–19 season.[57]

In August 2018, Fox Television Group CEO Dana Walden outlined how the network would operate following the transition to New Fox. The network will commission and acquire series from "independent" studios (such as Lionsgate, MGM Television, Sony Pictures Television, and Warner Bros., the last of which being a co-owner of The CW with CBS but not outright owning a major broadcast network). Walden noted that the vertical integration of the major broadcast networks (including Fox itself) with associated studios had limited opportunities for outside studios, and cited several top programs that were distributed by third-parties, such as The Big Bang Theory and This Is Us (produced by Warner Bros. Television and 20th Television for CBS and NBC respectively). There are also plans for Fox to acquire new pitches directly from their writers, and offer them to outside producers. As part of the transition, Fox aimed to gradually reduce the amount of scripted programming development coming from 20th Century Fox Television, although stalwarts such as The Simpsons will remain with the network.[57]

Following the completion of the sale, network head Dana Walden became chairwoman of Disney Television Studios and ABC Entertainment. AMC president Charlie Collier succeeded Gary Newman as chairman and CEO of Fox on November 1, 2018. Newman was expected to temporarily remain with Fox in a transitional role, in order to oversee the corporate transition.[58][59][60][61][62] The start of 2019 saw The Masked Singer premiere to Fox's highest ratings for a non-scripted premiere without an NFL lead-in since 2011, and record the largest-ever Nielsen ratings gain for a non-scripted series after three days of delayed viewership.[63][64][65] On January 30, 2019, Fox ordered a second season, while the season finale saw an average audience of 11.5 million viewers.[66][67]

With the completion of Disney's purchase the next day, the "New Fox" entity, officially named Fox Corporation, formally began trading on March 19, 2019.[48] At its 2019–20 upfronts, Fox announced 10 new scripted series for the upcoming season, with three (Almost Family, Bless the Harts, and Prodigal Son) slated for the fall lineup, as well as the second and third seasons of The Masked Singer — scheduled for October 2019 and February 2020 (premiering after Super Bowl LIV) respectively.[68][69][70] Fox also established a new in-house studio, Fox Alternative Entertainment, for investments in non-scripted formats. It is led by the network's president of alternative entertainment and specials Rob Wade, while its first production was season 2 of The Masked Singer (after season 1 was produced by Endemol Shine North America).[71]

Programming
As of 2015, Fox currently provides 19 hours of regularly scheduled network programming each week. The network provides fifteen hours of prime time programming to its owned-and-operated and affiliated stations on Monday through Saturdays from 8:00 to 10:00 p.m. and Sundays from 7:00 p.m. to 10:00 p.m. (all times Eastern and Pacific). An hour of late night programming is also offered on Saturdays from 11:00 p.m. to 12:00 a.m. Eastern and Pacific Time, a former hour of original comedy, but currently a repeat hour for primetime series (though scheduling for that hour varies depending on the market due to late local newscasts airing in the traditional 11:00 p.m./10:00 p.m. timeslot on some Fox stations). Weekend daytime programming consists of the paid programming block Weekend Marketplace (airing Saturdays from 10:00 a.m. to 12:00 p.m., although the block is not carried by all affiliates and, in some areas, is offered to another station in the market), and the hour-long Sunday morning political discussion show – and the network's only regular national news program – Fox News Sunday with Chris Wallace (airing from 9:00 a.m. to 10:00 a.m. Eastern and Pacific, although the timeslot also varies by market due to local news or public affairs programming).

Sports programming is also provided; usually on weekends (albeit not every weekend year-round), and most commonly airing between 11:00 a.m. and 4:00 p.m. or as late as 8:00 p.m. on Sundays (often airing for longer hours during the National Football League season, slightly less during NASCAR season); between 12:00 p.m. and 7:00 p.m. (during baseball, college football, and college basketball season) on Saturday afternoons; and during prime time on certain Saturday evenings. The Saturday prime time block if any sports programming is scheduled for a particular week on that night currently varies between occasional Premier Boxing Champions events, Major League Baseball, or NASCAR coverage in the late winter and early spring/summer, and college football coverage during the fall.
