Google's video homage to the drive-in theater (click on the movie ticket to watch) embodies the concept at its peak in the 1950s, when more that 5,000 drive-in movie theaters dotted the American landscape.
On June 6, 1933, Richard Hollingshead Jr. opened the first drive-in theater on Crescent Boulevard in Camden, New Jersey. Except he didn't call it a drive-in theater. That came later. He called it the "park-in" movie theater. The cost for a ticket: 25 cents per vehicle and 25 cents per person.
While the number of drive-in theaters in the US has dwindled to 366, according to the United Drive-in Theaters Association, there's something of a DIY revival today that echoes Mr. Hollingshead's own early tests in his driveway at 212 Thomas Avenue in Camden, New Jersey. Hollingshead used a 1928 Kodak projector to show home movies on a screen hanging between two trees in his yard.
