I still don't understand how companies are able to trademark normal english words, even ones that have been used in entertainment media before. I was baffled when Blizzard trademarked Diablo, and this is just as baffling. I heard that The Fast and The Furious was going to be called something with "Diablo" in the title, but had to change because of Blizzard. So why didn't Blizzard have to change their game name because of movies like El Diablo? Because they were the first to trademark it, not the first to use it?
