History
1968–1979: Early years
The station signed on the air on September 20, 1968. The original call sign was KACO, and it was owned by the Apollo Broadcasting Company. It aired an adult contemporary and middle of the road format. A fire at the transmitter took the station off the air in January 1970.Two months later, the station returned to the air, changed its call letters to KGRV, and relaunched as "Music for Groovy Adults," offering a more upbeat AC format. This lasted until 1972, when it once again changed call letters, this time to KKSS, and rebranded as "Kiss 108". By 1974, KKSS switched to country music. A year later, KKSS flipped to an R&B format, dubbed "Black in Stereo". In February 1979, KKSS altered its R&B format and adopted the moniker "Studio 108," with a hybrid disco music and R&B format, competing with WZEN.
1979–1997: CHUrban/UC
In June 1979, the call sign was changed to KMJM and rebranded as "The New Majic 108 FM, Where the Music is the Majic!". KMJM Was catered to both African-American and Caucasian-American listeners as the St. Louis market's first "CHUrban" station. At the time, the station was owned by Keymarket Communications.
