Redeeming the Dial

Blending cultural, religious, and media history, Tona Hangen offers a richly detailed look into the world of religious radio. She uses recordings, sermons, fan mail, and other sources to tell the stories of the determined broadcasters and devoted listeners who, together, transformed American radio evangelism from an on-air novelty in the 1920s into a profitable and wide-reaching industry by the 1950s.
