KCFM hit the air on March 27, 1955,[1][2] It was owned by the Commercial Broadcasting Company and broadcast from the Boatmen's Bank Building, relocating its studios and transmitter to 532 DeBaliviere in 1959.


After being an easy listening station for much of its life, Combined Communications bought KCFM in 1978 and relaunched it as an adult contemporary station, which on July 10, 1980, became KSD-FM. KSD-FM evolved into an AC/CHR hybrid (also known as Hot AC) format, under the moniker "KS94 FM". Then, in August 1987, KSD-FM dropped the Hot AC format for Classic rock as "The New 93.7 KSD-FM"; that format lasted until January 1999, when KSD-FM briefly went back to Hot AC as "Mix 93.7".[3][4] At noon on October 9, 2000, KSD switched to a country music format as "Better Country, 93.7 The Bull", soon after WKKX ("Kix 106") dropped country to become WSSM, "Smooth Jazz 106.5" (the station at 106.5 became 106.5 The Arch in April 2005), as due to a big ownership shakeup in 2000, Bonneville Radio ended up owning both competing country stations, thus opening up a spot for a competitor to longtime country station WIL-FM. The first song on "The Bull" was "The Thunder Rolls" by Garth Brooks.
