KVEO-TV, virtual channel 23 (UHF digital channel 24), is a dual NBC/CBS-affiliated television station licensed to Brownsville, Texas, United States and serving the Rio Grande Valley metropolitan area. The station is owned by Nexstar Media Group, which also operates Harlingen-licensed TBD affiliate KGBT-TV (channel 4.2) under a shared services agreement (SSA) with owner Mission Broadcasting. The two stations share studios on West Expressway (I-2/US 83) in Harlingen; KVEO-TV's transmitter is located in Santa Maria, Texas. On cable, KVEO-DT1 is available on Charter Spectrum channel 8, while KVEO-DT2 is carried on Spectrum channel 4.
KVEO-TV signed on the air on December 19, 1981. Before then, the area had been one of the few in the country without a full-time NBC affiliate; the area's original NBC affiliate, Weslaco's KRGV-TV (channel 5), had become a full-time ABC affiliate in 1976. The station was originally owned by a local group of investors called Tierra Del Broadcasting Corporation. In the interim, CBS affiliate KGBT-TV (channel 4) carried NBC programming on a secondary basis. The original owners sold the station to Valley Broadcasting in 1984, which in turn sold KVEO to Southwest Multimedia a year later. Southwest Multimedia would then sold it to Associated Broadcasters (later renamed Communications Corporation of America, founded by Thomas R. Galloway and D. Wayne Elmore) in 1990. KVEO-TV added a secondary affiliation with UPN in 1996, replacing previous secondary affiliate KRGV-TV; in 1999, the station lost UPN to XHRIO-TV in Matamoros.
On April 24, 2013, Communications Corporation of America announced the sale of its entire group (including KVEO-TV) to the Nexstar Broadcasting Group. The sale was completed on January 1, 2015.
On January 27, 2020, Sinclair Broadcast Group announced that it would sell the non-license assets of KGBT-TV (including its CBS affiliation and syndication contracts) to Nexstar as part of a settlement between the two companies over Sinclair's failed acquisition of Tribune 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-TV's affiliation with the network after 66 years; KGBT-TV's main 4.1 subchannel has since been inactive. In addition, Nexstar also announced that it would move KVEO-TV's operations from Brownsville to KGBT-TV's facility on West Expressway 83 in Harlingen within a few months.
