In many ways, Frasier is a textbook example of how to make a spinoff work. The creators took a great yet underused character from a beloved show, moved him to a new city, gave him a new job and surrounded him with strong supporting characters. In those crucial early seasons, he rarely made any reference to his days at that Boston bar, and visits by Woody and the gang simply didn't happen. After a while, many people watching Frasier simply stopped thinking about him as the guy from Cheers. The show ran for 11 seasons. It definitely began to run out of steam near the end, but that's bound to happen with 11 seasons of anything.
