It's not just Mickey: 10 characters and cultural works losing some copyright protection, from Peter Pan to Charlie Chaplin

• The original Mickey Mouse entered the public domain after Disney's copyright on the image expired.
• A trove of other cultural works published in 1928 also are losing copyright protection.
• Here are 10 notable songs, books, and other works and what they stood for.

Creators rejoice: The original Mickey Mouse is now in the public domain after Disney's copyright on the image expired on January 1.

The change only applies to the version of Mickey from the 1928 animated short "Steamboat Willie" and not his more modern likenesses, which are still protected by copyright law.
