Sites related to the USA's Sonny Bono Copyright Term Extension Act of 1998, which extends the term of copyright restrictions by 20 years. Sometimes called the "Mickey Mouse Copyright Act" by critics, since the Disney Corporation lobbied hard for it. Opponents pointed out that Congress had extended the terms of copyrights eleven times in the preceding fifty years, with the effect that no works created since 1923, such as the earliest Mickey Mouse cartoons, had ever passed into the public domain.
