Documentarian Ken Burns turns his camera on the history of radio, from the first experiments at the turn of the century to the golden age of the '30s and '40s. Rare newsreels, broadcast clips, and interviews with notables like Norman Corwin, Red Barber and Garrison Keillor are used to explore the medium and the men who fought for its development and its control. Jason Robards hosts. 120 min. Standard; Soundtrack: English Dolby Digital mono.
