 103.3 signed on in January 1993 as WLYZ, simulcasting WLWZ (103.9 FM)'s urban contemporary format to the Spartanburg part of the market as "Double Z".For history of the urban contemporary format on 103.9 prior to the sign-on of 103.3, see WTOB-FM.In late 1994, the station's then-owner, Emerald City Broadcasting, purchased WWMM (107.3 FM) and moved the urban format to the new station since it had a much stronger signal than the 103.3/103.9 simulcast.
