You should ask disney about the Public Domain. For a long time they have been making good use of it. Most of their movies are based on books in the public domain. Why? Because when a work is released into the public domain it no longer holds any copyright, and therefore anyone can do with it whatever they please. And most importantly – no money needs to be paid.
As Wikipedia states: ‘Works in the public domain are those whose intellectual property rights have expired, have been forfeited, or are inapplicable.’ This means that a lot of books are there to be explored, but also some movies, tv shows and other media. We gather them for you.
