A media franchise is like having a lot of toys that all belong to the same group. You might have some superhero toy action figures that are all part of the same movie or comic book story. Each toy has its own special story and characteristics, but they all work together to make the same big story.
For example, imagine you have a favorite cartoon that you watch every week. You might also see it as books, movies, and even video games. All of these things, even though they might be different versions of the story, are part of the same media franchise.
It's like having a bunch of different types of ice cream flavors, but they all belong to the same ice cream store. They might taste different and look a bit different, but they all come together and belong to the same ice cream store.
So, a media franchise is when one idea, story, or world is used in several different ways to explore the same idea or story. It's like having a big collection of toys or flavors, all part of the same group.
