ABC Development Corporation (also known as Associated Broadcasting Company) is a Filipino-owned media company based in Novaliches, Quezon City, Philippines. The company was spearheaded by the late Edward Tan, broadcasting and advertising veteran in 1992, when he led a group of investors that revived the Associated Broadcasting Company which was founded by Joaquin "Chino" Roces on June 19, 1960. Presently, it is owned by MediaQuest Holdings, Inc., a wholly owned subsidiary and part of the beneficial trust fund of the Philippine Long Distance Telephone Company headed by business tycoon Manuel V. Pangilinan.
Among its assets are the broadcast television networks TV5 and AksyonTV, sports network blocktimer AKTV which is aired over IBC 13, and the radio network Radyo5 92.3 News FM as well as the satellite television channels Colours, Hyper and Weather Information Network.
Joaquin "Chino" Roces, owner of the Manila Times was granted of a radio-TV franchise from Congress under Republic Act 2945 on June 19, 1960. He then founded the Associated Broadcasting Company and the channel "ABC 5" with the call sign DZTM-TV and its first studios along Roxas Boulevard, becoming the fourth television network established in the country. ABC operated radio and television services from 1960 until September 21, 1972 when President Ferdinand E. Marcos declared Martial Law. Both ABC and the Manila Times were forcibly shut down as a result.
New stockholders led by broadcast veteran Edward Tan and Chino Roces's son Edgardo then began the arduous task of resuming broadcasts. The Securities and Exchange Commission granted their application for an increase in capitalization and amendments to ABC’s articles of incorporation and by-laws. They were subsequently granted a permit to operate by the National Telecommunications Commission (NTC).
ABC inaugurated its new studio complex and transmitter tower in San Bartolome, Novaliches, Quezon City in 1990, and began test broadcasts by the end of 1991; officially returning on air as the ABC-5 on February 21, 1992, with ABC Development Corporation as the new corporate name. It's radio counterpart, Kool 106.7 was launched at the same time. Later, it acquired a new franchise to operate on December 9, 1994, under Republic Act 7831 signed by President Fidel V. Ramos.
In 1999, ABC was awarded the channel 47 frequency in Metro Manila, the last remaining UHF frequency in the market, with a powerful transmitting capacity, christening it DWDZ-TV. However, has been inactive since 2003.
Cojuangco era 
In October 2003, ABC was acquired by a group led by businessman Antonio "Tonyboy" Cojuangco, Jr. served as Chairman of the Philippine Long Distance Telephone Company (PLDT) from 1998-2004 and owner of Dream Satellite Broadcasting and Bank of Commerce, among other assets.
Its biggest achievement was when its flagship channel, ABC, won as the "Outstanding TV Station" award at the 2005 KBP Golden Dove Awards, with several other programs on the network also earning awards in their respective categories.
In early 2007, ABC suffered a setback when it implemented a series of budget cuts, primarily directed towards its news department, which laid off most of its employees.
On 2008, ABC-5 was rebranded as TV5 as it enters a partnership with MPB Primedia Inc., a local company backed by Media Prima Berhad of Malaysia as part of a long-term strategy to make the station more competitive. This caused the revitalization of its ratings from 1.9% in July 2008 (prior to the re-branding) to 11.1% in September 2009.
Acquisition by PLDT 
On October 20, 2009, Media Prima announced that it would be divesting its 70% share in TV5 and selling it to the Philippine Long Distance Telephone Company's broadcasting division, MediaQuest Holdings, Inc. to recover its assets from the global financial crisis. It was formally acquired on March 2, 2010 as announced by PLDT chairman Manuel V. Pangilinan. TV5 was reformatted on April 4, 2010 with a new lineup of programming and branding as the "Kapatid" ("sibling") network. Dream FM was retained under Cojuangco management with TV5 as licensee until June 2011.
On October 1, 2010, TV5 took over the management of MediaQuest's Nation Broadcasting Corporation stations; DWFM was re-launched as a TV5-branded news radio station on November 8, 2010, Radyo5 92.3 NewsFM, and DWNB-TV was re-launched as AksyonTV on February 21, 2011, a news channel based on TV5's newscast Aksyon.
Through co-owned Pilipinas Global Network Ltd., international channels Kapatid TV5 and AksyonTV International were launched in April 2011. The channels were available in Europe, Middle East, North Africa, Guam, and the United States.
Through affiliate Cignal, the network launched its own satellite television networks: lifestyle channel Colours, sports channel Hyper, and Weather Information Network. The channels were launched on April 14, 2012.
ABC Development Corporation CEO, Rey Espinosa, will set to step down to assume his new post as Associate Director of the First Pacific Company Ltd., PLDT's majority owner. He will be replaced by Noel C. Lorenzana, the current Head of the Individual Business for the PLDT Group. The move will be effective by June 1, 2013.
