Overview
WOAI-TV is a broadcast television station serving San Antonio, Texas, and the surrounding South-Central Texas market. The station broadcasts on channel 4 and has been affiliated with NBC since it began operation, making it one of the market’s longest-running network outlets. It also operates a CW-branded digital subchannel and presents its local programming under the News 4 San Antonio identity. The station is owned by Sinclair Broadcast Group and is operated alongside Fox affiliate KABB and CW affiliate KMYS, which is licensed to Kerrville and owned by Deerfield Media under arrangements that give Sinclair operational control. The stations share facilities in northwest San Antonio, while WOAI-TV’s transmitter is located in northwest Wilson County near Elmendorf. WOAI-TV first went on the air on December 11, 1949, as the first television station in the San Antonio market. It was launched by Southland Industries alongside WOAI radio, whose established NBC Red Network relationship helped secure the television station’s NBC affiliation. The WOAI call letters are unusual for a Texas station because the traditional division between W and K call signs was once positioned farther west than the Mississippi River; the radio station’s existing call sign was retained when the television service launched. During its earliest months, the station also carried selected programs from CBS, ABC, and DuMont, but those secondary affiliations moved to newer local stations as San Antonio’s television market developed. The station passed through several ownership groups during the second half of the twentieth century. Crosley Broadcasting announced its acquisition of the WOAI stations in 1965, and the broadcaster subsequently operated under the Avco name. After Avco decided to leave broadcasting, United Television, a subsidiary of 20th Century Fox, acquired WOAI-TV. Because the radio station had been sold separately and retained the WOAI call letters, the television station became KMOL-TV in December 1974. United later became associated with Chris-Craft Industries and BHC Communications. News Corporation’s Fox Television Stations acquired Chris-Craft’s television properties in a transaction announced in 2000 and completed in 2001. KMOL-TV was then exchanged to Clear Channel Communications, a transaction that reunited the station with WOAI radio and made it part of a San Antonio-based communications group. Clear Channel restored the WOAI-TV call sign in September 2002. The station was later transferred to Newport Television following Clear Channel’s 2007 divestiture of its television group. Ownership and regulatory restrictions led to a 2008 transaction in which High Plains Broadcasting held the station’s license while Newport continued to provide operating services. Sinclair acquired WOAI-TV in 2012. The transaction also brought the station into a San Antonio operating group with KABB and KMYS. Because federal ownership rules limited the number and combination of full-power stations that could be commonly owned in the market, KMYS was assigned to Deerfield Media while remaining subject to a Sinclair shared-services arrangement. The stations later consolidated sales, administrative, promotional, and newsroom functions in a shared northwest San Antonio facility. WOAI-TV remains an active NBC affiliate and local-news operation, combining network programming, syndicated and locally produced programming, weather coverage, sports content, digital publishing, and community-oriented reporting.
History
WOAI-TV began broadcasting on December 11, 1949, as San Antonio’s first television station. Southland Industries owned it alongside WOAI radio, and the television station inherited the radio outlet’s NBC relationship. The station initially carried some programming from CBS, ABC, and DuMont, but those secondary affiliations moved to other San Antonio stations as new competitors launched in 1950 and 1957. Crosley Broadcasting announced a $12 million purchase of the WOAI stations in 1965. After regulatory approval, Crosley assumed control, later operating its broadcasting interests under the Avco name. Avco announced in 1974 that it would leave broadcasting, leading to the sale of the television station to United Television, a 20th Century Fox subsidiary. Because WOAI radio had been sold to Clear Channel Communications and retained the call letters, the television station changed its identity to KMOL-TV on December 11, 1974. The sale was completed in November 1975. United subsequently became associated with Chris-Craft Industries and BHC Communications. Chris-Craft sold its television stations to News Corporation’s Fox Television Stations in a transaction announced in 2000 and completed in 2001. News Corporation exchanged KMOL-TV and KTVX in Salt Lake City to Clear Channel for WFTC in Minneapolis. Clear Channel took control of KMOL-TV in October 2001, reuniting it with WOAI radio. The historic WOAI-TV call sign returned in September 2002. Clear Channel announced the sale of its television group in 2006. The group was sold to Newport Television, controlled by Providence Equity Partners, with the transaction completed in 2008. Ownership restrictions involving Providence’s interest in Univision and San Antonio station holdings resulted in WOAI-TV’s license being transferred to High Plains Broadcasting. Newport continued to operate the station through a shared-services structure. In 2012, Newport and High Plains agreed to sell WOAI-TV to Sinclair Broadcast Group. Sinclair also acquired KABB, while KMYS was placed with Deerfield Media to address federal duopoly restrictions; Sinclair retained operational control of KMYS through a shared-services agreement. The deals closed in December 2012. A studio fire in March 2013 temporarily disrupted operations, but the station continued broadcasting through backup arrangements and returned to its downtown facility several days later. By 2014, WOAI-TV’s sales, promotional, executive, and news operations had been integrated into shared northwest San Antonio facilities with KABB and KMYS. The station has continued to expand and modernize its local service. It introduced local high-definition newscasts in 2009, later adding upgraded field-production capabilities. Its programming includes NBC’s schedule, local newscasts under the News 4 San Antonio brand, the San Antonio Living daytime program, Sports Sunday, weather and emergency coverage, and programming on its CW digital subchannel. WOAI-TV also has a long relationship with San Antonio Spurs coverage through NBC’s former NBA rights and later selected regional game packages.
