Singapore Radio began in 1936 with stations each broadcasting in its four official languages - namely Radio One (English), Radio Two (Malay), Radio Three (Chinese) and Radio Four (Tamil). The then owner - Singapore Broadcasting Corporation - launched a revamp campaign and started several stations targeting different segments of the population. Perfect Ten began in 1989 to play English hits for the youth, while its Chinese equivalent, Y.E.S. 93.3FM began broadcasting on 1 Jan 1990 at 9.33AM.
Y.E.S. 93.3FM began as an 18-hour station, broadcasting from 6.00AM to 12.00AM. Broadcasting hours were extended to 2AM in the early 1990s, making it the first Chinese radio station to offer music after midnight. It finally went 24 hours on 1 May 1994.
The Y.E.S. moniker was adopted in 1998. It is an acronym for Your Entertainment Station.
