Most programming was separate from its sister station, WDBC, with a few exceptions including simulcasts of Casey Kasem's American Top 40.
John Bulmer was forced to sell the Erie radio stations due to overlap in signals (during the time one could only own one AM and one FM in the same market).
The WFGO call letters of Froggy 94.7, formerly an oldies station, were originally moved over to 1330 when 94.7 became Bob-FM.
Later losing rights to use the Froggy moniker, the call letters were reverted to WFNN and it uses the branding "True Oldies 1330".
On September 10, 2007, the station returned to an all-sports format as "Fox Sports Radio 1330 The Fan".
