A discussion of the technological possibilities for communications, with emphasis on the use of satellites. Economic, legal, and regulatory problems, and the social implications of the innovations, are examined. Satellites can drastically change the economics of communications in magnitude and in form. The choices available will frequently involve more than economic factors, and it may be difficult to predict the relative social acceptance of the various alternatives. Among the innovations in communications that are examined are communications in business and to the home; recorded communications; public order surveillance; automatic identification; and tourism. 30 pp.
