partner in one duopoly became the junior partner in another, as well as the first instance involving a duopoly that was broken up legally terminating all operational ties with the junior partner); WABM was to be sold to a third-party buyer with which Sinclair would not enter into an operational outsourcing arrangement or maintain any contingent interest, other than a possible transitional shared facilities agreement until WTTO was able to move its operations from its Beacon Parkway studios to WBMA's facility in Hoover. On May 29, 2014, after informing the FCC that it had not found a buyer for WABM (even among the respective owners of WBRC, WVTM and WIAT that did not operate an existing duopoly in Birmingham, Raycom Media, Media General and LIN Media, the latter two of which were in the process of merging at the time), Sinclair stated that it would propose a surrendering of the WJSU and WCFT licenses, and migrate the WBMA simulcast to WABM's second digital subchannel on the basis that the latter's transmission facilities are superior to those of WCFT and WJSU (as a low-power station, WBMA-LD would not be affected as the FCC does not apply in-market ownership caps to low-power stations owned alongside any full-power station). After nearly a year of delays, Sinclair's acquisition of Allbritton was approved by the FCC on July 24, 2014, and completed one week later on August 1. On September 18, 2014, in preparation for the planned shutdown of WCFT and WJSU eleven days later on September 29 (the transaction would be suspended on Sinclair's asking by the FCC days prior to the shutdown after the group agreed to sell both stations to Howard Stirk Holdings, on the agreement that Sinclair would not enter into any operational arrangements with HSH for either station), WDBB added a simulcast feed of WBMA-LD on digital subchannel 17.2, replacing WCFT (which became a Heartland affiliate) as WBMA's Tuscaloosa repeater; WABM also added a simulcast of the WBMA on its 68.2 subchannel. Subchannel history WTTO-DT2/WDBB-DT2 On March 23, 2006, Sinclair Broadcast Group announced that it signed an affiliation deal with The Tube to carry the music video network on the digital subchannels of many of the group's stations. The channel launched on WTTO/WDBB's second digital subchannel, which launched on virtual channels 21.2 and 17.2 on June 15, 2006. On December 31, Sinclair dropped The Tube from the stations affected by
