WSB is a news/talk radio station in the United States. It is licensed to Doraville, Georgia and serves the Atlanta metropolitan area. They have a little mess with their names. Strictly saying there is a WSBB-FM 95.5 available on 95.5 MHz FM frequencies. And it has a sister radio station WSB AM 750, which is available on 750 kHz AM. WSBB is a full simulcast of WSB AM and both radio stations are owned by the Cox Media Group (privately held American conglomerate). Do not confuse WSBB-FM with WSB-FM, which is available on 98.5, broadcasts contemporary music and is owned by the Cox Media Group, too.
WSBB-FM is a reliable source of information for Atlanta metropolitan area in terms of news, weather and traffic. According to the statistics published on their website this is the most dominant and influential radio brand in Atlanta. Their audience is around 1 Mio. listeners per week. But in reality they have much more listeners as they are also available via a live stream so many people also listen to WSB online.
