This station first went on the air on September 9, 1973 using the call sign KTAN-FM, and it broadcast a top 40 rock and roll format.
KTAN-AM-FM was owned by Ken Ferguson (Huachuca Broadcasting).
Ken Ferguson died in a plane crash in 1977 and the station was sold, changing its call sign to KTAZ-FM to coincide with its use of Z-Rock as its music service.
In 1989, under GCS Broadcasting, the call sign was changed to KFFN.
Effective June 17, 2022, Cherry Creek Radio sold KZMK as part of a 42 station/21 translator package to Townsquare Media for $18.75 million.
