I'm trying to clear up my understanding of the words series, franchise and universe as applied to creative works.
Wikipedia's use of Multimedia Franchise suggests that a franchise can include multiple series and potentially incompatible cannons. This makes franchise a larger unit, but the retail usage tends towards a franchise being a smaller unit, such that a single McDonalds outlet is an instance of the franchise. Neither of these links really address the concept of a creative franchise although the multimedia franchise seems closest.
So, to put it into a few examples. How would the words series, franchise and universe be used to deal with;
- Star Wars: Original Trilogy, Prequel Trilogy, Sequel trilogy and various books.
- Spiderman: Comics, Sam Rani Films (2000s), Marc Webb films (2010 reboots), 1980s cartoons.
- Jurassic Park: Books, Jurassic Park 1-3 (1990s), Jurassic World 1-x, (2010s).
