In the 1950s, Americans moved to the expanding suburbs and embraced a culture of conformity and consumerism. The GI Bill helped millions of veterans buy homes and get educated on the government's dime, leading to the rapid growth of suburbs like Levittown. Suburban living became synonymous with the American Dream of home ownership. Television celebrated traditional family values and middle class life. Car ownership skyrocketed and the new Interstate Highway System made the country more mobile. Teenagers emerged as a distinct demographic with their own culture as rock and roll music became popular. Religious observance increased during this period of prosperity and social pressure to conform.
