The government officially dissolved RTS on 31 January 1980 and transferred its assets to the then-new Singapore Broadcasting Corporation, a statutory board under national supervision to free RTS from the administrative and budgetary constraints that had hampered its ability to upgrade broadcasting services to meet the growing expectations of local audiences. On 31 January 1984, SBC launched Channel 12, a new television service devoted to cultural programming. It also launched four radio stations: "Perfect 10", "YES" (airing Mandarin music), "Ria" (airing popular Malay music) and "Class 95" (initially airing classic hits). SBC began stereo broadcasting on its television channels on 1 August 1990.
