History
WCOS-FM signed on in March 1951 as the sister station of WCOS (1400 AM). It was Columbia's second FM station and originally broadcast on 97.9 MHz. Prior to 1963, it was on the air only during the evening hours. The separate programming featured Broadway showtunes, opera and classical music, along with news from the ABC Radio Network.

In the fall of 1963, the station began broadcasting in FM stereo and the hours were extended to the daytime. The morning show was a simulcast of 1400 WCOS, which was hosted by Bob Fulton, the long-time announcer for University of South Carolina Gamecocks football. After 9 am, the format was easy listening and beautiful music. The music was broadcast in mono until 6 pm, converting to stereo for the evening hours. In the late 1960s, WCOS-FM converted to a progressive rock format. Prior to the change, the station promoted the new format by announcing frequently that WCOS-FM was "going underground." By 1973, the station changed to country, adopting its longtime slogan "The Great 98." The country format has remained since.

In 1991, the station upgraded its signal by changing the frequency from 97.9 MHz to 97.5 MHz and increasing its power to 100,000 watts. That made it one of the strongest FM signals in the Columbia radio market.

In 1997, WCOS-AM-FM were acquired by Capstar, Inc. Then in 2000, Capstar, including WCOS-AM-FM, were acquired by San Antonio-based Clear Channel Communications. Clear Channel changed its name to iHeartMedia in 2014.

WCOS-FM is co-owned with sports radio station WCOS (AM), CHR/Top 40 station WNOK, variety hits station WLTY, urban contemporary station WXBT, Black Information Network station 105.5 W288CX, and talk radio station WVOC in the Columbia radio market.
