media tie-in

A media tie-in is a product, such as a book, video game, or merchandise, that is created to connect with a popular movie, TV show, or franchise. These products are often developed to enhance the audience's experience, promote the original content, or capitalize on its popularity. For example, a novel based on a blockbuster film or a action figure modeled after a character from a series are media tie-ins. They serve as supplemental material that leverages the existing fan base, providing additional storytelling or tangible memorabilia related to the familiar universe.
