In 1996, Sinclair merged with River City Broadcasting, owner of WSYX. Federal Communications Commission (FCC) rules at the time did not allow one person to own two stations in a single market. Sinclair kept the longer-established WSYX and nominally sold WTTE to Glencairn, Ltd. owned by former Sinclair executive Edwin Edwards. However, nearly all of Glencairn's stock was held by the Smith family, founders and owners of Sinclair. In effect, Sinclair still owned WTTE, and now had a duopoly in Columbus in violation of FCC rules. Sinclair and Glencairn further circumvented the rules by moving WTTE's operations into WSYX's Dublin Road studios under a local marketing agreement, with WSYX as senior partner. Glencairn owned ten other stations—all in markets where Sinclair also had a station. Sinclair was eventually fined $40,000 for its illegal control of Glencairn. The two companies attempted to merge in 2001 after the FCC allowed duopolies. However, the FCC would not allow Sinclair to repurchase WTTE. 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. WTTE thus remained under the banner of Glencairn, which was then renamed Cunningham Broadcasting. However, the Smith family still controls nearly all of Cunningham's stock, so Sinclair still effectively has a duopoly in Columbus. By nearly all accounts, Sinclair has used Glencairn/Cunningham as a shell corporation to evade FCC ownership rules.
