On the other hand, 3DB/3TT/TTFM/Mix/KIIS would have a terrible time trying to do a 90th anniversary logo. The number of different logos they’ve had through those years, good luck with that one.
A 30th anniversary of FM might be possible, but even then it’d be a schmozzle trying to coordinate them all into something as slick as the Fox 40th, especially given KIIS (and it’s predecessors) doesn’t have half the recognition in Melbourne as Fox does.
