Disney has been using Steamboat Willy in the beginning credits of their shows/movies for a while now. They are attempting to make it a Trademark (since the copyright wouldn’t be extended further). Since Trademarks must be defended, Disney will likely start suing anyone using Steamboat Willy on grounds of Trademark violation.

Commodore 64 gang rise up!
