KGBT-TV's roots lie in the 1941 establishment of KGBT radio, an independent radio station with a staff of eleven people. The station was owned by the Harbenito Broadcasting Company. KGBT became an affiliate of the CBS Radio Network in 1943. KGBT-TV signed on in 1953 as a CBS Television affiliate, mirroring its radio cousin. KGBT-TV was founded by Tichenor Media System, Inc., a regional conglomerate of Spanish-languageradio stations. Tichenor owned the KGBT radio station until 2003 when the company merged with Univision Communications. Before 1976, KGBT shared ABC programming with NBC affiliate KRGV-TV. When KRGV-TV became an ABC affiliate, KGBT-TV took on a secondary NBC affiliation until 1981 when KVEO-TV signed on. In 1986, Tichenor decided to exit the English-language broadcasting market by selling KGBT-TV to the Draper Holdings Business Trust, the owner of WBOC-TV in Salisbury, Maryland. In 1998, Draper sold KGBT-TV to Cosmos Broadcasting, the broadcasting division of the Liberty Corporation. Cosmos came directly under the Liberty banner in 2001 when Liberty sold off its insurance business. Liberty merged with Raycom Media in 2006. In August of that year, KGBT-TV was sold again to Barrington Broadcasting. In 2013, Barrington sold KGBT-TV to the Sinclair Broadcast Group as part of a larger deal which involved 18 television stations. The sale was completed on November 25. On January 27, 2020, Sinclair announced that it would sell WDKY-TV in Lexington, Kentucky and the non-license assets of KGBT to Nexstar Media Group as part of a settlement between the two companies over Sinclair's failed acquisition ofTribune Media, which was ultimately acquired by Nexstar. KVEO-TV assumed the CBS affiliation on 23.2 the next day, thus bringing an end to KGBT's affiliation with CBS after 66 years; the.1 subchannel is now inactive, but the station's other subchannels are still in operation.
KGBT's broadcasts became digital-only, effective June 12, 2009.

James was a veteran of the station's "glory days" during the late 1960s and 1970s when the station produced the top-rated newscast in the Rio Grande Valley.
