WCAY 620 signed on August 22, 1958 as Columbia's first Country music radio station. By the early 1970s, the station faced financial problems as WCOS-FM became the dominant Country station in the market. The station was sold, becoming WLFF with an Adult Standards format. In the mid-1980s, the station was sold again and became WTGH with an Urban Gospel/Inspiration format.
In 2003, WTGH was sold to Glory Communications, which kept the format but changed the call letters to WGCV. Glory Communications also owns WFMV and WQXL in the Columbia radio market.
