Modern audiences know a lot more about the inner workings of studios and who owns the rights to which characters than at any other time in history. This is due to the fact that, with the variety of iconic pop-culture characters out there, many of us wonder which of these figures are allowed to appear in which properties. One of the most famous examples of the 21st century is how The Avengers and the X-Men were all Marvel characters, yet there was a strict divide between their cinematic likenesses, as Marvel Studios owned the rights to The Avengers and 20th Century Fox owned the rights to the X-Men. This example is now moot, as The Walt Disney Company, which owns Marvel Studios, acquired 20th Century Fox and all of the characters they owned.
