National Amusements, Inc. was an American privately owned movie theater operator and mass media holding company incorporated in Maryland and based in Norwood, Massachusetts, controlled by the Redstone family. The company owned 69 theaters and 667 screens throughout the United States, the United Kingdom, and Latin America under several brands, such as Showcase Cinemas, Multiplex Cinemas, and Cinema de Lux. It was the controlling shareholder of Paramount Global.
National Amusements was founded by Michael Redstone, and later passed to his son Sumner Redstone. After his 2020 death, the company was passed to a trust led by his daughter Shari Redstone. After nearly 90 years of control by the Redstone family, in July 2024, David Ellison's Skydance Media announced its intent to acquire National Amusements and perform merger between Skydance Media and Paramount Global to form Paramount Skydance Corporation. The Federal Communications Commission (FCC) approved the merger of Skydance Media and Paramount Global on July 24, 2025, with the merger closing on August 7, 2025, with National Amusements being absorbed into Paramount Skydance.
