In television, any work derived from an existing show is known as a "spin-off." Sometimes, a series or an aspect of it resonates so powerfully with audiences that there is a demand for more stories. Sometimes, that comes in the form of a sequel series, picking up where the last show left off. Other times, a single character might be spun off into their own program, where the narrative focuses on them rather than the main characters from the show on which they debuted.

But you already know all that stuff because you're a fan of classic TV. And any fan knows that producers won't be satisfied when something is successful on TV until every last drop can be milked from it.

So can you tell the difference between these real spin-offs and the phony ones? In the crazy world of TV, all of them are believable, but only some of them are real.
