The station first signed on the air on August 28, 1959, at 100.9 FM under its original call letters
CHEC-FM. The station's call letters were changed to
CILA in 1979 and increased its power to 100,000 watts. In 1980, the station moved to its current frequency. In 1992, the station adopted its current call letters. The station had a
hot adult contemporary format until
2007 when the station shifted to
adult contemporary, the station's format change to adult contemporary occurred around the same time
CJBZ-FM shifted from
adult hits to
CHR/Top 40. This format change was to compete against rival station
CJOC-FM. This makes Lethbridge the largest Alberta market without a
hot adult contemporary station, having been overtaken from
Edmonton in February
2010, virtually the same time when
CKNO-FM signed on the air. The station has since moved back to a
hot AC sound. The station's branding at the time was
107.7 The River. On September 2, 2016, CFRV rebranded to
KiSS 107.7, with no change in format. ==External links==
