United States v. Paramount Pictures, Inc., 334 U.S. 131 (1948) (also known as the Hollywood Antitrust Case of 1948, the Paramount Case, the Paramount Decision or the Paramount Decree), was a landmark United States Supreme Court antitrust case that decided the fate of film studios owning their own theatres and holding exclusivity rights on which theatres would show their movies. It would also change the way Hollywood movies were produced, distributed, and exhibited. The Supreme Court affirmed (a District Court's ruling) in this case that the existing distribution scheme was in violation of United States antitrust law, which prohibits certain exclusive dealing arrangements.
