The Radio Act of August 13, 1912, provided for the licensing of radio operators and transmitting stations for nearly 15 years until Congress passed the Radio Act of 1927. From 1921 to 1927, there were continual revisions and developments and these still serve as the basis for current broadcast regulation. This book chronicles that crucial six-year period using primary documents. The administrative structure of the Department of Commerce and the personnel involved in the regulation of broadcasting are detailed. The book is arranged chronologically in three sections: Broadcast Regulation and Policy from 1921 to 1925; Congestion and the Beginning of Regulatory Breakdown in 1924 and 1925; and Regulatory Breakdown and the Passage of the Act of 1927. There is also discussion of the Department of Commerce divisions and their involvement until they were absorbed by the Federal Communication Commission. A bibliography and an index conclude the work.
