tie-in(redirected from tie-in, a)
A piece of media, such as a book, movie, or video game, that uses or expands on the core material or content of something else as part of a marketing strategy or campaign. These video game tie-ins are usually pretty crappy, but this one's actually not bad. I'm writing a novel that acts as a tie-in to the film.
