I have a 25th anniversary record I bought at a flea market in the late 1980's, it's a CBS special products LP, has some great country classics. WBIE FM 101.5, MARIETTA-Atlanta. I always knew 101.5 came from Shepherd's tower, but Wilder used to have his studios at 19 Atlanta St on the square, next to what is now the state probation office. There was an article posted right before his death in 1981 from the AJC on either this site or GRHOF, where he said he got offers to buy his stations from all around the country from the major players, but made the statement "if I quit working, I'll be dead". Ironically, he passed not too long later, and his estate took up one of those golden offers and thus, out with WBIE and in with WKHX, but the format has always been country in one form or another since.
With WFOM gone, we don't really have any Cobb county English speaking radio in any format, which is surprising, considering we have one of the most affluent populations (700,000 plus as of last census) but we're so served by ATL sticks it doesn't matter.
In the early days of WBIE and WFOM, Marietta was a day trip, like going to Callaway gardens, if you lived in ATL proper.
