Gilfillan (German studies and information literacy, Arizona State U.) notes that despite the ascent of television and film, radio has continued to evolve--and that an understanding of the medium requires a close examination of the artistic developments that preceded commercial acceptance. His book provides a cultural history of radio by focusing on German radio broadcasting, showcasing the artists and pioneers of the past century, illustrating how radio was used before and after World War II, and how broadcasters experimented to enhance the artistic and communications possibilities of radio.
