The station was launched on September 10, 1955 as KARD-TV as a independent station. In 1956, the station joined NBC after KEDD was shut down. In 1962, the station was purchased by Central Kansas Television (which owned KCKT (VHF channel 2) in Great Bend, KGLD (VHF channel 11) in Garden City and KOMC-TV (VHF channel 8) in Oberlin).
The call letters of all four of the Kansas State Network stations were changed on August 16, 1982 to help viewers think of the four stations as part of one large network. KARD changed its calls to KSNW, KCKT became KSNC, KGLD became KSNG and KOMC became KSNK. With the change, the stations became known as KSN.
