Lewis's book, which relates the civil wars between the principal figures in the invention and development of radio, is an achievement in its own right: finely detailed, engagingly written, and unexpectedly dramatic.

[A] compelling read for anyone with an interest in the history of radio and television.

A compelling tale that takes readers back to another era and shows us how our lives were transformed forever.

Empire of the Air is indispensable for anyone curious about the beginnings of broadcasting and there is more than enough personal drama and social and political history to make the book entertaining and informative for the general reader.

[Lewis] has all of the skills and instincts of a historian, a gift for clear description of complex technologies and a real passion for detail.

The lives of the two innovative technologists (Lee DeForest and Edwin Armstrong) and the entrepreneur (David Sarnoff) whose work led to the success of radio provide the basis for this well-researched and superbly written volume.
