Book excerpt: "The heart of David Weinstein's book examines DuMont's programs and personalities, including Dennis James, Captain Video, Morey Amsterdam, Jackie Gleason and The Honeymooners, Ernie Kovacs, and Rocky King, Detective. Weinstein uses rare kinescopes, archival photographs, exclusive interviews, trade journal articles, and corporate documents to tell the story of a "forgotten network" that helped invent the very business of network television."--Jacket.
