Drive-in cinema

A drive-in theater or drive-in cinema is a form of cinema structure consisting of a large outdoor movie screen, a projection booth, a concession stand and a large parking area for automobiles. Within this enclosed area, customers can view movies from the privacy and comfort of their cars. Some drive-ins have small playgrounds for children and a few picnic tables or benches.

The screen can be as simple as a wall that is painted white, or it can be a steel truss structure with a complex finish. Originally, a movie's sound was provided by speakers on the screen and later by an individual speaker hung from the window of each car, which would be attached by a wire. This system was superseded by the more economical and less damage-prone method of broadcasting the soundtrack at a low output power on AM or FM radio to be picked up by a car radio. This method also allows the soundtrack to be picked up in stereo by the audience on an often high-fidelity stereo installed in the car instead of through a simple speaker.

A partial drive-in theater – Theatre de Guadalupe – was opened in Las Cruces, New Mexico, on April 23, 1915:

Seven hundred people may be comfortably seated in the auditorium. Automobile entrances and places for 40 or more cars within the theater grounds and in-line position to see the pictures and witness all performances on the stage is a feature of the place that will please car owners.

The first movie shown by the Theatre de Guadalupe was Bags of Gold, produced by Siegmund Lubin. Theatre de Guadalupe soon was renamed De Lux Theater before closing in July 1916.

In 1921, a drive-in was opened by Claude V. Caver in Comanche, Texas. Caver obtained a permit from the city to project films downtown. With cars parked bumper-to-bumper, patrons witnessed the screening of silent films from their vehicles. In the 1920s, "outdoor movies" became a popular summer entertainment, but relatively few "drive-in" experiments were made due to logistical difficulties.
