. 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). Since FCC duopoly regulations forbid common ownership of more than two full-power stations in a single market from being under the same ownership, Sinclair spun off KMYS to Deerfield Media; however, Sinclair retained control of KMYS through a shared services agreement. In addition, while FCC rules disallow ownership of two of the four highest-rated stations in the same market, which normally precludes duopolies involving two " Big Four" network affiliates, Sinclair cited in its FCC purchase application that WOAI ranked as the fourth highest-rated station (behind KWEX-DT) and KABB the fifth-rated station in the San Antonio market in total day viewership. The Sinclair and Deerfield Media deals were consummated on December 3, 2012. KTVX, which had been a sister station to WOAI-TV since United Television acquired both stations in 1975, was sold to Nexstar, resulting in the two stations coming under entirely separate ownership and management for the first time in over 37 years. The operations of KABB and KMYS initially remained separate from WOAI-TV, with the two stations retaining competing news operations. 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; the incident occurred during NBC News coverage of the
