WOAI-TV (channel 4) is a television station in San Antonio, Texas, United States, affiliated with NBC and The CW.

In its early years of operation, it also carried programming from the three other major networks of the time: CBS, ABC and DuMont.

WOAI lost the CBS and DuMont affiliations to KEYL (channel 5, now KENS) when that station signed on in February 1950.

[6] On November 25, 1974, Avco, which had, at that time, decided to exit broadcasting, announced that 20th Century Fox, through its United Television subsidiary, would be acquiring WOAI-TV.

[8] The change was brought on by an FCC regulation in place at that time that prohibited non commonly-owned TV and radio stations in the same market from sharing the same base call sign.

[10] Chris-Craft Industries gained majority ownership of United in 1981, merging the group with BHC Communications (the owners of KCOP in Los Angeles and KPTV in Portland, Oregon).

News Corporation then traded KMOL and sister station KTVX in Salt Lake City to Clear Channel in exchange for WFTC in Minneapolis.

Not only did the purchase reunite KMOL-TV with WOAI Radio, but channel 4 also became the television flagship of the San Antonio-based conglomerate.

On November 16, 2006, after being bought by private equity firms, Clear Channel announced that it would sell all of its television stations.

Even without KNIC in the picture, both WOAI and KWEX were among the four highest-rated stations in the San Antonio market at the time of the Clear Channel sale (and remain so today).

On July 19, 2012, Newport Television/High Plains Broadcasting reached a deal to sell 22 of the company's 27 stations to Sinclair, Nexstar and Cox Media Group.

[17] On the morning on March 19, 2013, a fire started in offices located on the second floor of WOAI-TV's studios, which resulted in the evacuation of the station's staff and forcing channel 4 to carry the papal inauguration of Pope Francis from Vatican City for about six hours; with WOAI-TV unable to broadcast from the building, the station used a makeshift set in a nearby parking lot for that day's late afternoon newscasts, before temporarily moving to KABB/KMYS' facility on Babcock Road.

WOAI's subchannel 4.2 carries a package of select Spurs games, split with KENS-TV and produced by FanDuel Sports Network Southwest.

On September 16, 2009, WOAI-TV became the third television station in the San Antonio market (after KSAT and KENS) to begin broadcasting its local newscasts in high definition; with the change, the station introduced a new set for its newscasts as well as a modified version of its "big 4" logo (which was altered to a red, white and black color scheme).

In February 2012, WOAI introduced a storm chasing vehicle provided by Ancira, which is used during severe weather situations affecting south Texas.
