On February 28, 2013, Barrington announced that it would sell its entire group, including WPBN/WTOM, to Sinclair Broadcast Group. At the same time, WGTU/WGTQ were acquired by Cunningham Broadcasting. Sinclair also acquired the LMA with WGTU/WGTQ; all but one of Cunningham's stations are operated by Sinclair under LMAs. The sale was completed on November 25. Nearly all of Cunningham's stock is held by trusts for the Smith family, founders and owners of Sinclair. Thus, for all intents and purposes, Sinclair owns both stations. Cunningham, previously known as Glencairn, has long been used as a shell corporation to allow Sinclair to operate duopolies where Sinclair cannot legally own them. The Traverse City–Cadillac–Sault Ste. Marie market has only seven full-power stations, too few to legally permit a duopoly. Also, even if the market had enough full-power stations to allow a duopoly, a WPBN/WGTU duopoly still wouldn't be legal as both are among the top four stations in the market.
