Television is one of the most powerful forces man has ever unleashed upon himself. The quality of human life may depend enormously upon our efforts to comprehend and control that force. This book represents my small contribution in that direction. The responsibilities of the Federal Communications Commission, and my own interests, go well beyond traditional broadcasting issues to the regulation of telephone rates, communications satellites, allocation of frequencies for mobile radio, computer networks and many more. Such important and fascinating concerns have been largely excluded here in order to emphasize broadcasting matters.
