ABS-CBN (an initialism of its two predecessors' names, Alto Broadcasting System and Chronicle Broadcasting Network) is a Philippine commercial television and new media network that serves as the flagship property of ABS-CBN Corporation, a company under the Lopez Group. The network is headquartered at the ABS-CBN Broadcasting Center in Quezon City, with additional offices and production facilities in 25 major cities including Baguio, Naga, Bacolod, Iloilo, Cebu, and Davao. ABS-CBN is colloquially referred to as the Kapamilya Network; this branding was originally introduced in 1999 and was officially introduced in 2003 during the celebration of its 50th anniversary. ABS-CBN is the largest media company in the country in terms of revenues, assets, and international coverage.
The network shut down for the first time in September 1972, due to the Martial Law declared by then-President Ferdinand Marcos. It resumed broadcast on September 14, 1986, after the People Power Revolution.
On March 10, 2020, in the wake of the World Health Organization-declared COVID-19 pandemic that had also spread across the Philippines, as well as President Rodrigo Duterte's declaration of state of public health emergency after the first local transmission of the coronavirus was confirmed, ABS-CBN announced that it would temporarily suspend its admission of studio audience in tapings for its game, talk, variety and reality shows, including Magandang Buhay, It's Showtime, ASAP Natin 'To, Banana Sundae and the second season of the Philippine version of South Korean game show I Can See Your Voice, to provide safety and well-being to its artists, crew and production teams. The aforementioned shows would, however, continue to air in production without a studio audience.
Then, on March 15, 2020, ABS-CBN temporarily suspended production of its entertainment shows, after the entire Luzon was put under a enhanced community quarantine (partial lockdown). Among the prime time shows affected included Pamilya Ko, FPJ's Ang Probinsyano, Make It with You (later canceled without completing its story in June 2020) and A Soldier's Heart, which were all put on hold from March 16 until May 2020. The network aired reruns of some teleseryes and other programs including 100 Days to Heaven, May Bukas Pa, On the Wings of Love, The Legal Wife, Got to Believe, Walang Hanggan, Wildflower, Wansapanataym, iWant Originals Series, Tubig at Langis, Your Face Sounds Familiar Kids Season 1, Pilipinas Got Talent Season 6, Bayani, Hiraya Manawari and Sine'skwela.
On May 5, 2020, the network was forced to cease operations, alongside sister channel ABS-CBN S+A and radio stations DZMM AM 630 and MOR 101.9, after the National Telecommunications Commission (NTC) issued a cease and desist against the network. This became a result of the expiration of the legislative franchise a day prior. The network went off air at exactly 7:52 pm Philippine Standard Time.
Its programming resumed on cable-and-satellite channel Kapamilya Channel, which was launched on June 13, 2020, originally being available on cable providers who are members of the Philippine Cable and Telecommunications Association (PCTA) (including Sky Cable) as well as satellite providers Sky Direct (until June 30) and G Sat, and later expanded to Cignal and SatLite on October 21, 2020.
On July 10, 2020, the network's franchise application has been officially denied by the members of the House of Representatives, particularly the Committee on Legislative Franchises, after a 70–11 vote.
On September 10, 2020, the NTC issued an order that authorizes it to recall all of the TV and radio frequencies and channels that were assigned to ABS-CBN and its related radio and local TV stations.
On October 6, 2020, its programming was returned on free TV through a blocktime agreement with ZOE TV on a new channel: A2Z Channel 11. It was officially launched on October 10, 2020.
