The station was originally WMPS-FM and had offered a classical format during the 1960s and 1970s. That was until October 1976 when it flipped to a Rhythmic Contemporary Hit Radio hybrid format that featured Disco. Even after Disco's demise they still continued to add Dance and Pop/Rock product throughout the 1980s but would evolve to Urban contemporary format by the end of that decade. It was purchased by Chancellor in the late 1990s along with sister station WDIA and former competitor KJMS. Today the station continues to dominate the Memphis Urban radio wars against KXHT, who has shifted back to a Rhythmic direction.
