To get around this limitation, extensions such as those listed above have been passed. In 1998, the [[Sonny Bono]] Copyright Term Extension Act (aka the "Bono Act") increased copyright terms to 70 years after the artist's death. It is often called the "[[Mickey Mouse]] Act" due to the law setting the public domain cutoff at 1923, a year close to the emergence of Disney's popular cartoon characters. In ''Eldred v. Ashcroft'' (2003), the Supreme Court ruled in favor of the Bono Act, claiming that the Constitution's "limited" could mean a term of any length.
