The only reason that I mentioned writers, artists, and producers was to show you that Family Guy has no conection to the Simpsons. Also, when I mentioned Futurama I had no intention of implying, nor, did I imply that it is a spin-off of the Simpsons. I simply said that you might have confused it as being a spin-off.
A spin-off is when they take a character from a show and make it into another show. Family guy does not have that nor any conection to Simpsons. It is a cartoon about a disfunctional familly, not a spin off; merely in the same genre as the Simpsons. Do you meen to tell me that every Cop show is a spin off of NYPD blue? Or every sitcom with a similar setting is a spin off of another one?
You sir, are to one that does not know the meaning of a spin-off. Take Frasier for example, that is a spin-off of Cheers.
