Campbell v. Acuff-Rose Music, Inc. is a landmark Supreme Court case from 1994 that clarified the application of the fair use doctrine in copyright law, specifically regarding transformative works. The case involved rapper Luther Campbell's use of the song 'Oh, Pretty Woman' in his parody 'Pretty Woman' and determined that parody can qualify as fair use even if it has a commercial purpose. This decision has significantly influenced how copyright and fair use are understood in journalism and creative expression.
