The station signed on the air on September 1, 1955, as WGKA-FM. Owned by Glenkaren Associates, it was the FM counterpart of WGKA (1190 AM), with studios at 1140 Peachtree Street NE. WGKA-FM was the first full-time FM classical music station in Atlanta.

​

In 1971, the General Cinema Corporation acquired WGKA-AM-FM. Even though it was a movie theater chain, GCC wanted to branch out into broadcast media. The classical music remained on the AM station, while the FM station became WZGC (referring to the last two letters in General Cinema) in 1972. WZGC began as an album-oriented rock station, which switched to Top 40 in March 1973, calling itself "Z-93."

​

In the 1970s, many radios still only received AM signals. WQXI was one of the leading Top 40 stations in Atlanta, but as FM listening increased, WZGC gained an audience. The station was acquired by First Media Corporation in 1976.

​

In the 1980s, the AM Top 40 stations switched to other formats, leaving WZGC as Atlanta's only contemporary hits station. Then, in 1986, WAPW (Power 99.7) debuted with its own popular Top 40 format, with WZGC's ratings declining as a result. The station switched to a rhythmic contemporary format during the summer of 1987.

 

In late 1988, the decision was made to change the station's format totally, and General Manager David Meszaros was imported from the company's Boston Classic Rocker, WZLX, and on January 3, 1989, the station flipped to Classic Rock, while retaining the "Z-93" moniker.  Program Director Tony Mathes, who was also brought in from WZLX, remembers the kickoff airstaff as (Barry) Chase and (Scott) Woodside in mornings, Robbie Spears in midday, Bob Bailey in afternoon, Steve Mapel at night, and Scott Evans and others in overnight.

 

Infinity Broadcasting acquired WZGC in 1992; Infinity was renamed CBS Radio in December 2005.

​

The name change to "Dave FM" and format switch to adult album alternative came at 5 p.m. on July 21, 2004.

​

CBS announced that WZGC would flip to all sports in October 2012. Dave's final day of programming, which started on September 29 after a three-day radiothon for Children's Healthcare of Atlanta, consisted of the on-air staff hosting final shifts (including Steve Craig, Jill, Mara Davis, Charles, Yvonne Monet, Sully, Renee, and Margot).  The station ran on automation until the flip at 2 p.m. on October 24.

​

On February 2, 2017, CBS Radio announced it would merge with Entercom. Entercom has now changed its name to Audacy.
