The station signed on for the first time on September 1, 1994, originally carrying Fox programming.[2] After that network moved to the newly established KFQX in June 2000, the station would affiliate with UPN, and stayed with that network until folding in September 2006. After KGJT's subsequent affiliation with the new MyNetworkTV programming service, its programming became available on KREX-TV's digital signal.
On January 20, 2008 at approximately 8:45 a.m., a fire knocked KREX, KFQX and KGJT off the air. The station's building and 50 years worth of archives were a total loss. Following the fire, KGJT began to simulcast KREX-TV's signal, except for Colorado Rockies baseball games on Sundays. KGJT resumed a separate schedule with MyNetworkTV programming towards the end of 2008.
KGJT airs newscasts from its sister station, KREX-TV. The simulcasts only include the weekday morning newscast (5–7 a.m.)[3]
