Tradition
There are many different things that can be called a movie in the world that we all live in these days. A movie can be something that actors and directors work on for years at a time to come up with what they think is the perfect product to put in movie theaters all over the world. Another thing that some people call a movie is just a home video that they take themselves with a video camera that they have purchased at a previous date. This is how some people keep up with memories of their kids and other people.
