The station has historically been one of the most listened to in Singapore; in a 2025 survey,Nielsen reported that the station had an average of 1.22 million listeners.[1]
In December 1989, Singapore Broadcasting Corporation (SBC) announced plans for two new radio stations to launch in 1990, in honour of SBC's 10th anniversary and Singapore's 25th anniversary of independence; aMandopopCHR station on 93.3 (which would serve as a Chinese counterpart to English CHRPerfect 10, which launched earlier that year), and an unnamed"MOR" station on 95.5.[2] The Mandopop station launched on 1 January 1990 as YES 933, also known as Radio 6;[3] at launch, the station had nine deejays on four-to-five-hour shifts, and aired fewer commercials than that ofRadio 3.[4]
YES 933 began as an 18-hour station, broadcasting from 06:00 to 00:00. 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.[5]
On 20 January 2017, the station moved fromCaldecott Hill to Mediacorp's new headquarters atOne-north.

Retrieved14 July 2025.On day one, Gao Meigui surprised Peifen with a variety of cat-themed items, including a bowl and Pusheen postcard. On the second day, she (Peifen) was surprised by Siau Jiahui and Tan Ting Fong, who gave her what appeared to be multivitamins. On day three, Zhu Zeliang and Lim Pin Juen met her in the hallway, saying that the biggest surprise was them - the hosts of the 10pm to midnight show - waking up so early for her, and presented her a bottle of wine. The next day was Joey Tay, and Peifen was once again surprised to see a colleague arrive early in the morning. She gave Peifen a bottle with the latter's name on it. Hazelle Teo and Evelyn Tan gifted her an Aesop handwash the following day, and Peifen said she couldn't read the women's letter to her or she would cry. It was Kenneth Chung and Jeff Goh on day six that had Peifen closest to tears with their framed collage with photos of the three of them.
