In 2001, after the FCC allowed duopolies, Sinclair tried to acquire Glencairn outright. However, the FCC would not allow Sinclair to repurchase WTTE for two major reasons. First, the FCC does not allow duopolies between two of the four highest-rated stations in a single market. Also, the Columbus market, despite its relatively large size, has only seven full-power stations—too few to legally permit a duopoly. Glencairn was renamed Cunningham Broadcasting but is still effectively owned by Sinclair because nearly all of its stock is owned by trusts controlled by the Smith family. This situation is one of many that has led to allegations that Cunningham is simply a shell corporation used by Sinclair to circumvent FCC ownership rules. Sinclair would later acquire WKRC-TV in 2012, reuniting the station with WSYX.
