Excellent resource
Excellent DVD for information on early Radio. Covers the competition between Sarnoff, Armstrong, DeForest, Edison, and many others. Describes the early competition and monopolies, and the attempts at first breaking them up, i.e. Red and Blue network, etc. Discusses overseas broadcasts, shortwave receivers, rise and fall of entrepreneurs of early Radio.
