ABS-CBN Broadcasting Center

The ABS-CBN Broadcasting Center in Diliman, Quezon City, Philippines is the oldest headquarters of ABS-CBN. It occupies an area of approximately 34,000 square meters adjacent to ELJ Communications Center. It was originally built in 1968 and was then the most advanced broadcast facility in Asia. Today it is now the country's largest and most technologically advanced media facility.Built as the headquarters of ABS-CBN, the center has since seen several management changes, such as a takeover by RPN and sister stations IBC and BBC in 1973, the addition of a fourth tenant, the government station GTV in 1974, and then the departure of RPN, IBC, and BBC in 1979 and the entry of NMPC and BB in 1980 which accompanied the remaining tenant MBS. From 1986 to 1992, the reopened ABS-CBN and PTV, along with PBS, shared the Broadcast Center and following PTV's departure in 1992, ABS-CBN has since regained full control of the facility.History1968-1972: First era under ABS-CBNThe broadcasting center, conceptualized by ABS-CBN's then-President Eugenio Lopez Jr., began construction in 1966 and was opened on December 18, 1968. Prior to the opening, ABS-CBN held headquarters in two buildings: the ABS building in Roxas Boulevard for ABS-CBN's Manila TV stations at that time, DZAQ-TV 3 and DZXL-TV 9, and the Chronicle Building in Aduana, Manila for its Manila radio stations. With the opening, ABS-CBN's radio and TV operations were housed in one building. ABS-CBN would soon give away the Roxas Boulevard studios to Kanlaon Broadcasting System or KBS (now known as Radio Philippines Network or RPN), which then took Channel 9 and prompted ABS-CBN to switch frequencies from Channels 3 and 9 to Channels 2 and 4.
