The NMPC was started out before the time of martial law when they acquired the facilities of the Voice of America in Malolos, Bulacan in 1965 and steadily brought the old complex up to standards by a steady overhaul, fine-tuning, and outright replacement of outmoded equipment and machines. The NMPC operated the Voice of the Philippines, VOP, on both medium wave-918 kHz and shortwave 9.810 mHz transmissions. In 1975, the NMPC obtained DZRB-FM. With this new station and some provincial stations that came under its wings earlier, the NMPC was a network and effectively covered a wide range of the Philippine listenership.[1]
After ABS-CBN was closed and the PBS was abolished to give way for the Bureau of Broadcasts (BB), the government through NMPC started to broadcast its own television station on Channel 4 as "Government Television" (GTV) under Lito Gorospe and later by then-Press Secretary Francisco Tatad.
The BB and the NMPC were brought under one administrative roof in 1980 when the Office of Media Affairs was created to provide a loose union for both networks within the Broadcast Plaza (now ABS-CBN Broadcasting Center) along Bohol Ave. in Quezon City.
At that time, Tatad was succeeded by Gregorio Cendana as the new Minister. NMPC relaunched GTV as the Maharlika Broadcasting System (MBS). All networks became the backbone of the Marcos propaganda.
After the People Power Revolution, the Office of Media Affairs, as well as the NMPC itself (along with the BB) were abolished to make way for the creation of the Office of the Press Secretary (OPS) through Memorandum Order No. 32 on September 1, 1986.[1][2]
