Shortly after Fox Entertainment Group's February 22, 2006 announcement of the formation of MyNetworkTV, WWWB was announced as the network's Charlotte affiliate. Sister station WJZY had already decided to join The CW, a network created out of CBS Corporation and Time Warner's decision to shut down UPN and The WB, effective that September. It would not have been an upset had WWWB been chosen, however. CW officials were on record as preferring the "strongest" WB and UPN affiliates, and Charlotte had been one of the few markets where the WB and UPN affiliates had both been relatively strong ratings performers. WWWB's affiliation with MyNetworkTV made Charlotte the first city in the nation with a duopoly involving affiliates of both The CW and MyNetworkTV.
