National Amusements, Inc. is an American privately owned movie theater operator and mass media holding company incorporated in Maryland and based in Norwood, Massachusetts.

On June 10, 1987, the company became the majority owner of the original incarnation of Viacom,[4] a former CBS subsidiary syndicating television programs to stations around the United States.

[6] In March 2005, due to Viacom's declining stock price, National Amusements announced that it would split its media subsidiary into two companies that would remain under its control, which was completed on December 31.

[14] The following year, National Amusements planned to sell $390 million of notes to refinance a large part of the company's bank owed debt.

[15] In 2019, it was announced that the multinational media conglomerates controlled by National Amusements — Viacom and CBS Corporation — would re-merge to form a new company named ViacomCBS.

They also share some of the corporate identities of Showcase and have XPlus & De Lux rooms in selected cinemas, as well as fully reclining seats.
