What is this?
In this section I spotlight several groups of stories told with multiple mediums. Halo for example utilizes video games, books, short films, and comics to tell its story. Many franchises already transcend one form of media. I use the term "film" or "book" franchises to refer to the form of media that started the franchise, or for which it is best known (a.k.a. James Bond as a film franchise).
Many franchises (with some exceptions) try to create a canonical chronology within the different media. This means that each work of media consists on the same timeline with little or no contradictions. Basically it's the idea that the fictional world has a "true" history, and the canonical media fits in this history. This is true of franchises like Star Wars and most newer video game franchises. Some franchises are selective on which media they consider canon, and others (especially superheroes) have multiple canons (Gold Age, Silver Age, etc). On this site I try to list just the canonical media, with a few minor exceptions which I will point out individually.
