A primarily American institution (though it appeared in other countries, such as Japan and Italy), the drive-in theater now sits on the verge of extinction. During its heyday, drive-ins could be found in communities - both large and small. Some of the larger theaters held up to 3,000 cars and were often filled to capacity on weekends. The history of the drive-in from its beginnings in the 1930s through its heyday in the 1940s and 1950s to its gradual demise in modern-day America is thoroughly documented here: the patent battles, community concerns with morality (on-screen and off), technological advances (audio systems, screens, etc.), audiences, and the drive-in’s place in the motion picture industry.
