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.
