Over the twenty-year span of the 1940s and 1950s, a growing sense of separation and resistance to the mainstream culture developed, characterized by distinctive food, slang, music, dress, and sexual behavior. By studying the mores of their culture, we understand the impact of consumerism and of the professionalization of advice-giving. The behavior of teenagers became increasingly separate from the mainstream and ultimately oppositional, leading to the even more overt rebellion of the 1960s.

By looking in particular at the magazines they read and the letters they wrote, as well as the peculiar vision expressed in hundreds of guidance films, we gain new insight into what made their culture work and, by implication, we better understand the changes in the larger American culture at mid-century.
