A spinoff in television is a new series containing characters or settings that originated in a previous series, but with a different focus, tone, or theme. For example, the series Frasier was a spinoff of the earlier series Cheers: the character Frasier Crane was introduced as a secondary character on Cheers, and became the protagonist of his own series, set in a different city, in the spinoff. Spinoffs are particularly common in sitcom. A related phenomenon, not to be confused with the spinoff, is the crossover.
