 WLNZ changed to CHR/Top 40 first as "Z-92" and later as "The Ape" WGOR (as in "gorilla") in 1989, but found its ratings success against WVIC limited and its advertising revenue even worse.One more unsuccessful format followed - smooth jazz and new-age music as WXMX "The Mix" from 1991 to 1993, before the station debuted what would become its most successful format yet.In 1993, 92.1 FM became WWDX ("92-1 The Edge"), a modern rock station and the first such commercial radio station in Michigan in this format outside the Detroit area.
