The station first signed on the air on April 17, 2003 as KCBU, operating as an independent station; it was originally owned by Cocola Broadcasting. Univision Communications bought the station in October 2004 and entered into an outsourcing agreement with Equity Broadcasting (which Univision's principals held a stake in at the time) to operate the station. At that time, channel 32 swapped affiliations and call signs with what was then KUTH (Utah's original full-power Univision affiliate on channel 12, licensed to Logan, Utah, which became KUTF in 2005) and became the new Univision affiliate.
