A timely book, for the public seems to have little actual knowledge of invention and development that is here to stay. This book really does ""present television"" in a much simpler and easier way than the somewhat didactic title would suggest. It consists of a series of articles by experts on every phase, and yet it is done in terms for the layman. Technical descriptions are in abc form, illustrated by diagrams. The problems implicit in the subject, financial and physical, indicate the need for public understanding and cooperation. Devices already are beginning to get the better of the limitations. The book increases general knowledge without being technical. Market specialized.
