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 the deal due to new educational programming regulations put into effect by the FCC that The Tube not immediately comply with by inserting E/I-compliant programming within its schedule, effectively putting the burden on local stations to carry programs that complied with the regulations; the network ceased operations on October 1, 2007, due to several factors likely including the discontinuance of the Sinclair carriage deal.
