In 1994, WGZB added Urban Adult Contemporary WLSY-FM (now WMJM) to its group of stations, giving the combination broader demographic reach by targeting the age 30+ audience, while WGZB targeted the age 12-35 group.

In 2004, WGZB's license was changed from Corydon to Lanesville so that the tower could be moved closer to Louisville and raised taller, eliminating much of the signal problems that the station had due to the low ERP.
