Price Communications presided over the collapse of its entire radio portfolio including WWKB and filed for Chapter 11 bankruptcy in 1992. After reorganization, WWKB was sold to Keymarket Communications in 1994. Around the same time, Keymarket acquired one of WWKB's longtime rivals, WBEN, from locally based owners at a premium price. Keymarket then sold both WWKB and WBEN to St. Louis-based River City Broadcasting in 1995. Sinclair Broadcast Group acquired WWKB and WBEN in 1996 through its purchase of River City. A year later, Sinclair bought WGR, bringing three of Buffalo's heritage AM stations under its portfolio. In 1999, Sinclair decided to divest its radio stations, selling most of them, including WWKB, WBEN and WGR, to Entercom Communications.
