History

The station signed on the air in March 1970. Originally, the call sign was WWMC, licensed to Moncks Corner and broadcasting at 3,000 watts. In the mid-1990s, WNST "New Star" played hot adult contemporary music under the name "Star 105". In December 1998, WCOO switched to rhythmic oldies, becoming "Cool 105.3". Soon, WCOO made big ratings gains at the expense of long-time AC station 102.5 WXLY. WXLY recovered but WCOO continued to improve. In January 2004, WCOO changed to its current format.
