 A screening room is a small theater, often a private one, such as for the use of those involved in the production of motion pictures or in a large private residence.The etymology of the term "movie theater" involves the term "movie", which is a "shortened form of moving picture in the cinematographic sense" that was first used in 1896 and "theater", which originated in the "...late 14c., [meaning an] "open air place in ancient times for viewing spectacles and plays".The term "theater" comes from the Old French word "theatre", from the 12th century and "...directly from Latin theatrum [which meant] 'play-house, theater; stage; spectators in a theater'", which in turn came from the Greek word "theatron", which meant "theater; the people in the theater; a show, a spectacle", [or] literally "place for viewing".
