THE FULL IMPACT OF SATELLITE COMMUNICATION WILL BE REALIZED ONLY WHEN IT BECOMES FEASIBLE TO SPACECAST DIRECTLY INTO HOMES, FACILITATING INEXPENSIVE LONG-DISTANCE CALLS AND ENABLING CONFERENCES TO BE HELD VIA TELEPHONE AND CLOSED-CIRCUIT TELEVISION. BUSINESS TRAVEL WILL DIMINISH. SPACE COMMUNICATION, BY INCREASING THE FLOW OF INFORMATION AND ITS SPEED OF AVAILABILITY AND BY BYPASSING THE EDITORIAL PROCESS, CAN PRODUCE A LESS INFORMED, RATHER THAN A BETTER INFORMED, PUBLIC OPINION, AND MAY CREATE TENSION DUE TO HASTY DECISIONS. THERE WILL BE TECHNICAL PROBLEMS OF FREQUENCY ALLOCATION, COMPATIBILITY OF STANDARDS, AND CONTROL OF PROGRAMS AND LEGAL PROBLEMS OF COPYRIGHT AND PROTECTION AGAINST COMMERCIAL EXPLOITATION. MAJOR ARTISTIC AND POLITICAL EVENTS WILL BE VIEWED WORLD-WIDE, SIMULTANEOUSLY, REDUCING PAROCHIALISM AND XENOPHOBIA. COMMUNICATION SATELLITES WILL AID EDUCATION, ESPECIALLY IN DEVELOPING COUNTRIES AND FACILITATE INTERLIBRARY EXCHANGE OF INFORMATION. THEY SHOULD ALSO CREATE A MUTUAL FLOW OF INFORMATION BETWEEN THE DEVELOPED AND THE DEVELOPING NATIONS. INFORMATION FROM THE LATTER SHOULD COVER NORMAL DEVELOPMENTS IN THE NEWS, NOT JUST CRISIS SITUATIONS. AN APPENDIX LISTS PARTICIPANTS. THIS DOCUMENT IS BASED UPON PAPERS SUBMITTED TO THE UNESCO MEETING OF EXPERTS ON THE USE OF SPACE COMMUNICATION BY THE MASS MEDIA (PARIS, DECEMBER 6-10, 1965) AND IS AVAILABLE FROM UNESCO, PLACE DE FONTENOY, PARIS-7E, FRANCE.
