Editing WZGC (section)

===Top 40 (1973–1989)===
In March 1973, the format switched to [[contemporary hit radio]] calling itself "Z-93".

In the 1970s, many radios still only received AM signals. [[WQXI (AM)|WQXI]] and [[WGKA|WGST (920 AM)]] were 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.<ref>[https://www.americanradiohistory.com/Archive-BC-YB/1978/C-Radio-Broadcasting-Yearbook-1978-Full.pdf Broadcasting Yearbook 1978 page C-51]</ref>

In the 1980s, the AM top 40 stations switched to other formats, leaving WZGC as Atlanta's only contemporary hits station. Then, in 1986, [[WWWQ|WAPW (99.7 FM)]] 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 1988.
