Mickey Mouse will be public domain soon—here’s what that means

On January 1, 2024, we'll see the expiration of the copyright for Steamboat Willie—and with it Disney's claim to the film's star, Mickey Mouse. The copyrights to Superman, Batman, Disney's Snow White, and early Looney Tunes characters will all fall into the public domain between 2031 and 2035.

Most copyrighted works become commercially worthless within a decade or two. But a small minority of famous works from the 1920s and 1930s were still generating significant revenues in the 1990s. Retroactively extending copyright terms meant an enormous windfall for the companies and families that owned the copyrights.
