WSB-FM (98.5 FM, B98.5FM) is an Atlanta radio station. Along with several other Atlanta radio stations, WSB-FM is owned by Cox Enterprises' publicly-traded subsidiary Cox Radio, and is the group's flagship FM station. It is the only Atlanta FM radio station to continue to share a callsign with local TV and AM radio stations (WSB AM and WSB-TV), and one of the few such triopolies (under the same ownership) left in the entire U.S..

As of January 2010, WSB-FM broadcasts a split format. Monday thru Friday afternoons, the station broadcasts an Adult Contemporary format. From 3 pm on Friday until 7 Sunday, WSB-FM broadcasts 1980s pop music under the Big 80s Weekend banner. WSB-FM broadcast 80s weekends from 2001-2003, and all-1970s weekends during the mid-1990s. During the holiday seasons from 2004 forward, the station plays all-Christmas music from the day after Thanksgiving to Christmas. Prior to 2007, its main competitor was Atlanta's other AC, Peach 94.9 (which became Lite FM in 2002).
