WEAF, the radio call letters which for nearly a quarter of a century designated a broadcasting station famous for its pioneering achievements, ceased last November to have its old significance. WNBC are the new call letters. This book is an excellent record of the four years during which this station was the experimental radio broadcasting medium of the American Telephone and Telegraph Company. 

The author indicates that the WEAF experiment aided the development of radio broadcasting in three ways: First, in the scientific and technological field. Second, in the emphasis of a high standard for radio programs. Third, in determining the means whereby radio broadcasting could support itself. When WEAF changed hands from the American Telephone and Telegraph Company to new ownership, public reaction to almost every type of broadcast had been tested, network broadcasting had been established and the economic basis upon which nationwide broadcasting now rests had been founded. 

A trail had been blazed that thereafter could be followed without hesitation. In so far as radio broadcasting is concerned, this book is a significant chapter in communication history. A Multichannel Microwave Radio Relay System} BEYER, T . J . GRIESER, F . A . POLKINGIIORN.
