A copyright is legal protection of any original work, including writing, art, music, film, choreography, architecture, photography, and even computer programs. Any work that is original and can be tangibly recorded is copyrightable. The best part about copyright protection is that it takes effect as soon as the work is recorded. The bad part is that people infringe on copyrights all the time. Check out Avvo's Legal Guides to find out how to register and protect your copyright.
