A really interesting thread, I never knew that Mork and Mindy was a spinoff from Happy days!

[andy-hughes]

I would discount The Simpsons as a spin-off.

By definition, a spin-off has to use established characters in a new format - like Green Green Grass and Rock And Chips - both using characters from Only Fools And Horses.

The Simpsons was a segment in the Tracy Ullman show, but it has simply expanded into a show of its own - it has not 'spun off' in any way.

My vote would be Frazier - from Cheers.

It doesn't win the prize but also from happy days was Laverne and Shirley and Joanie loves Chachi
