A summary of 18 months' investigation into the potential uses of telecommunications in the public interest is presented. Areas investigated include public TV and radio, cable TV, television translaters, instructional fixed television service, satellite communications and interconnections. Public hearings were held in eight cities and more than 100 representatives of telecommunications industries testified. Questionnaires were mailed to all delivery systems operators, and appropriate officials of other states were asked to comment on their telecommunications policies. The committee issued specific legislative recommendations in all areas listed above, sought to define the role of governmental and community agencies, and made suggestions for the use of systems. Appendixes include summaries of appropriate current legislation, maps showing locations of public TV and radio stations in California, a summary of Federal Communications Commission regulations on cable TV, and a report on a satellite technology demonstration.
