media properties into separate publicly traded companies. Once the corporate separation was finalized on June 29, 2015, WFAA became part of Tegna, which was structured as the legal successor of the old Gannett and assumed ownership of the original company's non-publishing assets (including the broadcasting unit and most of its digital media properties); the Gannett Company, meanwhile, was re-established as a new company absolved of all existing debt that retained its predecessor's newspapers (including the company's flagship publication, USA Today) and select digital assets not acquired by Tegna. On September 25, 2020, WFAA would gain a sister station when Tegna acquired KMPX (channel 29) from Estrella Media which airs its Estrella TV network over that station. The sale was completed on November 20 with KMPX moving most of its internal operations days later into WFAA's Communications Center Studios on Young Street. While KMPX continues to serve as an Estrella TV affiliate, the signal is utilized to provide a full-market high definition simulcast of WFAA's main channel (which remains on VHF channel 8) for those who only have a UHF antenna. The deal also includes a five-year affiliation agreement between Estrella and Tegna, as well as an option for Estrella to purchase WFAA's VHF license. If the five-year agreement to sell the station to Estrella is carried out in full, Estrella would purchase the license and transmitter assets of WFAA, and the two stations would swap physical channels, with WFAA then taking KMPX's FCC facility ID and in technicality, KMPX moving to the channel 8 facility ID established in 1949. Pending sale to Cox Media Group On February 22, 2022, Tegna announced that it would be acquired by Standard General and Apollo Global Management for $5.4 billion. As a part of the deal, WFAA and KMPX, along with their Austin sister station KVUE and Houston sister stations KHOU and KTBU would be resold to Cox Media Group. Radio WFAA (AM) WFAA (AM), which would eventually serve as the sister radio station to WFAA television, first signed on the air on June 26, 1922. The station had long participated in a time-sharing arrangement with Fort Worth radio station WBAP, which was maintained as the latter operated at various frequencies; it originally began in 1922, when WBAP (which first went on the air on May 2 of that year, nine weeks before WFAA began operations) transmitted at 630 kHz and continued until 1927,
