Book excerpt: During the 1920s and 1930s, changes in the American population, increasing urbanization, and innovations in technology exerted major influences on the daily lives of ordinary people. Explore how everyday living changed during these years when use of automobiles and home electrification first became commonplace, when radio emerged, and when cinema, with the addition of sound, became broadly popular. Find out how worklife, domestic life, and leisure-time activities were affected by these factors as well as by the politics of the time. Details of matters such as the creation of the pickup truck, the development of radio programming, and the first mass use of cosmetics provide an enjoyable read that brings the period clearly into focus. Centering its attention on the broad masses of the population, this animated reference resource emphasizes the wide variety of experiences of people living through The Roaring Twenties and The Great Depression. Readers will be surprised to discover that some of the assumptions we have about the lives of average Americans during these eras are historically inaccurate. A final chapter provides a unique look at six American communities and gives a vivid sense of the diversity of American experience over the course of these tumultuous years.
