99X is a radio station in Atlanta, Georgia, USA, streaming an alternative rock radio format branded as 99X, which began on full-power station WNNX (now WWWQ) FM 99.7 in late October 1992. The station was taken off-air when Q100 (WWWQ) was moved to 99.7 from 100.5 (now WNNX), but returned to W250BC FM 97.9, and then moved to W256BO FM 99.1 (which is now W255CJ FM 98.9). It was taken off-air again on the last day of August 2012, and replaced the following day with "98-9 the Bone", but none of the on-air staff were fired as commercial broadcasters typically do when changing a format, indicating that 99X (or something similar) may make a second resurrection on another Cumulus Media station in the area. 99X would be relaunched on W255CJ on January 1, 2016.
