Channel 2 was inserted into Fredericksburg in 1986, leading to a twelve-way battle for the allotment, which had the potential to serve Austin and San Antonio from one transmitter.

In 1993, the Federal Communications Commission review board favored a consortium of former San Antonio Spurs owner Red McCombs and broadcast executive Bob Roth.

Appeals from the comparative hearing process continued until 1998, when the commission awarded the permit to Corridor Television, a merger of the McCombs–Roth group and a company owned by the Tawil family of Austin.

The group contracted with the Belo Corporation, owner of TV stations in both cities, to run channel 2, which began broadcasting as a UPN affiliate on August 3, 2000.

KBEJ changed its original sequential call sign to KCWX and became the CW affiliate in the San Antonio market.

[3] With Fredericksburg located almost halfway between two media markets, the availability of a VHF station that could potentially serve both attracted attention from prospective owners.

Administrative law judge Edward Luton made his initial decision on who should be granted the channel out of six contenders in June 1989; he selected Stonewall Television, owned by Marquis Whittington and Robert Simmons.

On October 20, 1995, Roth and two executives from the Hearst Corporation took a trip to scout the area and view the proposed transmitter site.

[6] In 1996, Fredericksburg Channel 2 merged with one of its five competing applicants: Global Information Technologies of Austin, a company owned by Carmen and Saleem Tawil.

[12] In 1998, UPN had dropped the Hill Country Paramount Network for K13VC on six days' notice because K13VC, unlike the previous affiliate, had cable carriage.

[13] In addition to a UPN affiliation, Corridor contracted with Belo, which owned Austin's KVUE and San Antonio's KENS, to operate channel 2 under a local marketing agreement.

[16] UPN initially designated KBEJ as its San Antonio affiliate, leading Time Warner Cable to deny the station must-carry on its Austin system.

It was not until August 2, 2001, that KBEJ made an appearance on Time Warner Cable's Austin system after pressure from viewers and an agreement with Belo.

[27] Sinclair Broadcast Group disclosed in its 2009 annual report for 2009, released in March 2010, that it had signed the month before to move the CW affiliation to KMYS—the former KRRT—on September 1, 2010.

[27] In 2021, KCWX began airing a package of local high school football games in the San Antonio area.
