In 2000, when 99.3 became a simulcast of The Buzz 105.5, WJSX continued in the smooth jazz format but changed its call sign to 99.3's now former WSAX.
Two years later, WMID-FM, along with sister stations WZBZ, WGBZ and WMID were sold to Equity Communications in Atlantic City.
This included signs on the boardwalk's famous tram cars advertising both frequencies.
On August 26, 2013, WAIV swapped formats and call signs with sister station WSNQ.
In June 2023, Equity Communications sold WAIV to Mighty Voice Broadcasting.
