What is a spin-off?
A spin-off is something that comes (is made) from something else. Typically, it is used to describe companies, TV shows, or even product ideas. As an example, the U.S. sitcom show called "Frasier" was a spin-off show of the earlier show called "Cheers". Kelsey Grammer (playing Dr. Frasier Crane) was the star of the Frasier show, but in Cheers, he was a patron of the Cheers bar. In both, he was a Psychiatrist. So, in the Cheers show, his character was part of the whole Cheers show (sharing time with the other actors/characters), but in the Fraser show he was the center of attention and the shows premise revolved around his work as a psychiatrist.The United States can be considered a spin-off of the European & Great Britain countries, and in many ways, the Protestants could be considered a spin-off of the Catholic church.
