Well, the first highly recognizable example of tie-ins that comes to my mind involves the Star Wars franchise. Over the decades dozens of tie-in novels have been written about the Rebel Alliance fighting the evil Galctic Empire. A large portion of those don't have the main characters from the movies in them and a large number of fans will argue that they are not cannon, but they still take place in the Star Wars universe and are written in such a way that their events don't retcon the movies.
