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. 987 began in 1989 to play English hits for the youth, while its Chinese equivalent, YES 933 began broadcasting on 1 January 1990 at 09:33. The Malay equivalent, Ria 897 began in December of the same year.

Initially, YES 933 was also known as Radio 6.^[1] At launch, the station had nine deejays on four to five hour shifts and aired fewer commercials than that of Radio 3.^[2]

YES 933 began as an 18-hour station, broadcasting from 06:00 to 24:00. Broadcasting hours were extended to 02:00 in December of the same year, making it the first Chinese radio station to offer music after midnight. It finally went 24 hours on 1 May 1994.

In 1997, 93.3 was the most-listened radio station in Singapore for the fifth year since 1993, with almost a million listeners every week, attributed to its uniqueness which catches the attention of listeners, combined with music, deejays and creative jingles.^[3]

On 20 January 2017, the station moved from Caldecott Hill to Mediacorp's new headquarters at One-north.
