Communications industry revenues presently represent approximately 2 percent of the GNP and are growing substantially faster than the GNP. The important question thus arises as to what capital resources will be available to support continued growth in the Seventies---a question of particular interest to the data communication user, whose needs are projected to expand at an explosive rate. By 1980, this growth could occur in any of the following areas: • Continued use of the existing analog telephone network as well as new data services on the Picturephone network; • New digital private line facilities offered by the existing carriers; • Expansion of Western Union facilities and service offerings; • Domestic satellite systems; • Private line and switched facilities of the special service common carriers; • Possible joint use of data on CATV systems.
