In the late 1940s, radio’s popularity had a strong impact on film. Not only were 1948 and 1949 high points in radio listenership, but with the mass migration to the suburbs, radio offered Americans an inexpensive entertainment alternative to the movies (as it had during the Great Depression). As a result, many people stayed home and listened to radio programs until TV displaced both radio and movies as the medium of national entertainment in the mid-1950s. The movie industry responded in a variety of ways.

First, with growing legions of people gathering around their living-room TV sets, movie content slowly shifted toward more serious subjects. At first, this shift was a response to the war and an acknowledgment of life’s complexity, but later movies focused on subject matter that television did not encourage. This shift began with film noir in the 1940s but continued into the 1950s, as commercial movies, for the first time, explored larger social problems such as alcoholism (The Lost Weekend, 1945), anti-Semitism (Gentleman’s Agreement, 1947), mental illness (The Snake Pit, 1948), racism (Pinky, 1949), adult–teen relationships (Rebel without a Cause, 1955), drug abuse (The Man with the Golden Arm, 1955), and—perhaps most controversial—sexuality (Peyton Place, 1957; Butterfield 8, 1960; and Lolita, 1962).

These and other films challenged the authority of the industry’s own prohibitive Motion Picture Production Code. Hollywood adopted the Code in the early 1930s to restrict film depictions of violence, crime, drug use, and sexual behavior and to quiet public and political concerns that the movie business was lowering the moral standards of America. (For more on the Code, see Chapter 16.) In 1967, after the Code had been ignored by producers for several years, the Motion Picture Association of America initiated the current ratings system, which rated films for age appropriateness rather than censoring all adult content.

Second, just as radio worked to improve sound to maintain an advantage over television in the 1950s, the film industry introduced a host of technological improvements to lure Americans away from their TV sets. Technicolor, invented by an MIT scientist in 1917, had improved and was used in movies more often to draw people away from their black-and-white TVs. In addition, Cinerama, CinemaScope, and VistaVision all arrived in movie theaters, featuring striking wide-screen images, multiple synchronized projectors, and stereophonic sound. Then 3-D (three-dimensional) movies appeared, although they wore off quickly as a novelty. Finally, Panavision, which used special Eastman color film and camera lenses that decreased the fuzziness of images, became the wide-screen standard throughout the industry. These developments, however, generally failed to address the movies’ primary problem: the middle-class flight to the suburbs, away from downtown theaters.
