On December 3, 2018, Nexstar announced it would acquire the assets of Chicago-based Tribune Media—which has owned CBS affiliate WHNT-TV (channel 19) since December 2013—for $6.4 billion in cash and debt. Nexstar was precluded from acquiring WHNT directly or indirectly while owning WZDX, as FCC regulations prohibit common ownership of more than two stations in the same media market, or two or more of the four highest-rated stations in the market. (Furthermore, any attempt by Nexstar to assume the operations of WHNT through local marketing or shared services agreements would be subject to regulatory hurdles that could delay completion of the FCC and Justice Department's review and approval process for the acquisition.) As such, Nexstar decided to sell WZDX to a separate, unrelated company to address the ownership conflict. WHDF does not rank among the top four in total-day viewership and therefore is not in conflict with existing FCC in-market ownership rules, thus, WHDF was retained by Nexstar and will merge their operations into WHNT's studios.) On March 20, 2019, Tysons, Virginia-based Tegna Inc. announced it would purchase WZDX from Nexstar upon consummation of the merger, as part of the company's sale of nineteen Nexstar- and Tribune-operated stations to Tegna and the E. W. Scripps Company in separate deals worth $1.32 billion; this would make WZDX the first television property in Alabama for Tegna and a sister station to NBC affiliate WBIR-TV in Knoxville and the duopoly of NBC affiliate WXIA-TV and MyNetworkTV affiliate WATL in Atlanta. WHDF was not included in the sale, with Nexstar intending to form a new duopoly involving WHNT. The sale was approved by the FCC on September 16 and was completed on September 19, 2019.
