KCWO-TV (channel 4) is a television station licensed to Big Spring, Texas, United States, serving the Permian Basin area as an affiliate of The CW Plus.

Until January 2019 as KWAB-TV, the station operated as a satellite of Odessa-licensed NBC affiliate KWES-TV (channel 9), then owned by Raycom Media.

KWAB-TV was a straight simulcast of KWES-TV; the only on-air references to the station were during Federal Communications Commission (FCC)-mandated hourly legal identifications.

[3] KCWO began operations in January 1956 as KBST-TV, owned by the Big Spring Herald along with KBST radio (1490 AM).

The radio station was eventually sold to the Snyder Corporation (co-owned by Ted Snyder, who later acquired KARN in Little Rock, Arkansas, and B. Winston Wrinkle), while a half interest in KBST-TV was transferred to Dub Rogers' Texas Telecasting, owner of KDUB-TV in Lubbock (now KLBK-TV) and part-owner of KVER-TV in Clovis, New Mexico (now KVIH-TV).

Soon afterward, the station took the KWAB callsign (for Webb Air Force Base), and switched from simulcasting KDUB to KPAR-TV (now KTXS-TV) in Sweetwater.

These stations were accused of fraudulent billing, program and transmitter log fabrication, main studio violations, failure to make required technical tests, and other issues.

The cash-and-stock merger transaction valued at $3.6 billion—in which Gray shareholders would acquire preferred stock currently held by Raycom—required divestment of either KWES or KOSA due to FCC ownership regulations prohibiting common ownership of two of the four highest-rated stations in a single market (as well as more than two stations in any market).
