A marquee is most commonly a structure placed over the entrance to a hotel, theatre, casino, train station, or similar building.
The current usage of the modern English word marquee, that in US English refers specifically to a canopy projecting over the main entrance of a theater, which displays details of the entertainment or performers, was documented in the academic journal American Speech in 1926: "Marquee, the front door or main entrance of the big top."
The word marquise was also used to refer to various objects and fashions regarded as elegant or pleasing, hence: a kind of pear (1690), a canopy placed over a tent (1718), a type of settee (1770), a canopy in front of a building (1835), a ring with an elongated stone or setting, a diamond cut as a navette (late 19th century), and a style of woman's hat (1889).
The larger size of the sign and text, combined with the flashing lights and color, made the façade easily visible to fast-passing cars.
The mild climate of certain locations, such as the American West Coast, also permitted the use of lightweight materials such as porcelain and plastics in marquees.
