Copyright provides legal protection for creators of original works like artists, writers, and musicians. It promotes creativity by allowing creators to control how their works are used. Copyright exists automatically when something is created and lasts for the creator's lifetime plus 70 years. Some key aspects of copyright include:
- Works can't be copyrighted but ideas can.
- Users should seek permission before using copyrighted works or use copyright-free materials. Fair use allows limited use of copyrighted works for purposes like education without permission.
- Works in the public domain are no longer copyright protected and can be used by anyone. This includes most works published before 1923.
