In 1998, the United States Congress passed the Sonny Bono Copyright Term Extension Act. Following up on a similar law passed in 1976, the law increased the amount of time works of corporate authorship would be protected under copyright law, extending the protection for existing copyrighted works for an additional 20 years, summing out at 95 years from the date of creation. The law was also referred to as the Mickey Mouse Protection Act, after its most significant proponent, the Disney Corporation. Mickey Mouse, first appearing on film in 1928, was at risk of falling out of copyright protection, and so Disney used its significant financial and political power as a major American business to lobby Congress to extend their ownership of the cartoon mouse.
