Media franchise
Multimedia franchises usually develop through a character or fictional world becoming popular in one medium, and then expanding to others through licensing agreements, with respect to intellectual property in the franchise's characters and settings. As one author explains, "For the studios, a home-run is a film from which a multimedia 'franchise' can be generated; the colossally expensive creation of cross-media conglomerates predicated on synergistic rewards provides an obvious imperative to develop such products." The trend later developed wherein franchises would be launched in multiple forms of media simultaneously; for instance, the movie The Matrix Reloaded and the video game Enter the Matrix were produced at the same time, using the same actors on the same sets, and released on the same day. Several other franchises throughout the 2000s had movies and games released within days of each other, including  King Kong, Star Wars, Harry Potter, DC Comics, Marvel Comics, The Lord of the Rings, The Chronicles of Narnia, Pirates of the Caribbean, and Transformers.
