But Listening In is more than a history. It is also a reconsideration of what listening to radio has done to American culture in the twentieth century and how it has brought a completely new auditory dimension to our lives. Susan Douglas explores how listening has altered our day-to-day experiences and our own generational identities, cultivating different modes of listening in different eras; how radio has shaped our views of race, gender roles, ethnic barriers, family dynamics, leadership, and the generation gap. With her trademark wit, Douglas has created an eminently readable cultural history of radio.
