Why was SIMPP formed?
SIMPP was formed by filmmakers who opposed movie monopolization. They wanted to curtail the growing power of the major Hollywood movie studios (Paramount, MGM, Warner Bros., Twentieth Century-Fox, and RKO), which not only owned the largest film factories in the world, but also controlled the largest theater chains in all parts of the United States. SIMPP assisted the government in its antitrust case against the major studios until it became illegal for the film studios to own movie theater chains.
