...comfort of their cars. Some drive-in theater managers added children's playgrounds between the screen and the first row of cars. Concrete patios for lawn chairs were available at some drive-in theaters.

Originally, audio 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 This system was superseded by the more economical and less damage-prone method of broadcasting the soundtrack at a low output power on AM or FM Radio to be picked up by a car radio.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 monaural through a simple speaker.

History

The drive-in theater was the creation of Camden, New Jersey, chemical company magnate Richard M. Hollingshead, Jr., whose family owned and operated the R.M. Hollingshead Corporation chemical plant in Camden. In 1932, Hollingshead conducted outdoor theater tests in his driveway at 212 Thomas Avenue in Camden. After nailing a screen to trees in his backyard, he set a 1928 Kodak projector on the hood of his car and put a radio behind the screen, testing different sound levels with his car windows down and up. Blocks under vehicles in the driveway enabled him to determine the size and spacing of ramps so all automobiles could have a clear view of the screen. Following these experiments, he applied August 6, 1932 for a patent of his invention, and he was given U.S. Patent 1,909,537 on May 16, 1933. (Seventeen years later, that patent was declared invalid by the Delaware District Court.)

Hollingshead's drive-in opened in New Jersey June 6, 1933 on Admiral Wilson Boulevard at the Airport Circle in Pennsauken, a short distance from Cooper River Park. He advertised his drive-in theater by saying, "The whole family is welcome, regardless of how noisy the children are". It only operated for three years, but during that time the concept caught on in other states.
