ABS-CBN was seized by the Office of Press Secretary and the National Media Production Center and DZXL-TV Channel 4 was renamed DWGT-TV Channel 4 (GTV-4), the government channel. KBS, IBC and RBS were later allowed to operate with limited three-month permits. ABS-CBN was seized from the Lopez family and Eugenio Lopez Jr., president of ABS-CBN, was imprisoned. By late 1973, RBS, which was then under blocktimer Philippine Productions, was sold to Felipe Gozon, who was also the lawyer of Robert Stewart, because foreigners were not allowed to own businesses in the Philippines. RBS later changed its name to GMA Radio-Television Arts (now GMA Network), popularly known as GMA-7.
