Tie-in

A tie-in work is a work of fiction or other product based on a media property such as a film, video game, television series, board game, web site, role-playing game or literary property. Tie-ins are authorized by the owners of the original property, and are a form of cross-promotion used primarily to generate additional income from that property and to promote its visibility.

Types

Common tie-in products include literary works, which may be novelizations of a media property, original novels or story collections inspired by the property, or republished previously existing books, such as the novels on which a media property was based, with artwork or photographs from the property. According to publishing industry estimates, about one or two percent of the audience of a film will buy its novelization, making these relatively inexpensively produced works a commercially attractive proposition in the case of blockbuster film franchises. Although increasingly also a domain of previously established novelists, tie-in writing has the disadvantages, from the writers' point of view, of modest pay, tight deadlines and no ownership in the intellectual property created.
