Although Clear Channel's San Antonio radio cluster is located in Northwest San Antonio, off of I-10, WOAI-TV remained based in its downtown studios on Navarro Avenue. On April 20, 2007, Clear Channel sold its entire television group to Providence Equity Partners-controlled holding company Newport Television; the group deal was finalized on March 14, 2008.However, channel 4 continued a news partnership with its former radio sister, and the two stations continued to share a website for two years afterward.Not only did the purchase reunite KMOL-TV with WOAI, but channel 4 also became the television flagship of the San Antonio-based conglomerate.
The station moved its digital signal from its pre-transition UHF channel 58, which was among the high band UHF channels (52-69) that were removed from broadcasting use as a result of the transition, to UHF channel 48, using PSIP to display the station's virtual channel as its former VHF analog channel 4.
WOAI-TV carries the entire NBC programming schedule.
This effectively made High Plains Broadcasting a front company for Newport Television in a relationship similar to that between Mission Broadcasting and Nexstar Broadcasting Group as well as between Cunningham Broadcasting (and later Deerfield Media) and the Sinclair Broadcast Group.
On December 17, 2007, WOAI debuted a slightly altered logo.
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).
When KRRT (channel 35, now KMYS) dropped its affiliation with the United Paramount Network (UPN) to join The WB in January 1998, KMOL began carrying UPN programming during the overnight hours; at the time, Chris-Craft had owned a 50% interest in UPN.WOAI-TV and WOAI radio are among the few broadcast stations located west of the Mississippi River that utilize a call sign that begins with a "W"; this designation was "grandfathered" when the Federal Communications Commission issued regulations requiring radio stations west of the Mississippi River to be assigned call letters starting with a "K," and stations east of the Mississippi to calls beginning with a "W." The station has been an NBC affiliate since its sign-on, due to WOAI (AM)'s longtime affiliation with the NBC Red Network; however, it originally also carried programming from the three other major networks of the time: CBS, ABC and Du Mont.WOAI lost the CBS and Du Mont affiliations to KEYL (channel 5, now KENS) when that station signed on in February 1950; the two stations continued to share ABC programming until KONO-TV (channel 12, now KSAT-TV) signed on in January 1957.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.WOAI-TV was among the six that would be sold to Sinclair, making it a sister station to Fox affiliate KABB (channel 29) and CW affiliate KMYS (channel 35).News Corporation then traded KMOL and sister station KTVX in Salt Lake City to Clear Channel in exchange for WFTC in Minneapolis.
