Unlike a telephone or telgraph cable, a broadcast, once sent out over the air, can only be “stopped” at the receiving end. If the potential listeners have radio receiving sets able to pick up the broadcast, it can only be stopped by causing such radio interference as to make it difficult or impossible to listen to the original broadcast. Over the years, several nations have assumed the large cost of producing such interference, or “jamming,” so as to prevent their citizens from listening to the broadcasts of other nations. An expensive and often inefficient technique, jamming was then believed preferable to allowing unrestricted and uncensored international communication by radio. Mr. Ranjan Borra, who was associated with All India Radio and with the Voice of America for several years and is currently on the staff of the Library of Congress describes both the background and some of the encouraging recent developments in the field of jamming and other impediments to international broadcasting.  相似文献

In the introduction to Charles Woodliff's “Catch Me if You Can” in the Fall, 1965 issue of the Journal it was, prophesied that it would be not “the last that will be published on the question of the proper curriculum for training professional broadcasters.” In this issue, on the preceding pages, is an article by Professor John Pennybacker answering Professor Woodliff's article disagreeing with the one that started it all, Pennybacker's “Working with Universities.” The following comment by Woodliff is intended only as a brief comment upon Pennybacker's “Leadership and the Educator: The Middle Way” and does not, of course, attempt to make full reply in this brief form. Professor Woodliff (Assistant Professor in the Department of Radio‐Television‐Film at the University of Denver) hopes that the dialogue between him and Dr. Pennybacker represents their respective points of view fairly—and that other positions will be heard from in the future. The airing of these points of view is not just another rehash of the old “liberal arts vs. professionalism” debate. Recent surveys have shown that broadcasting education has not yet made its mark on the industry—if it is to do so in the future, teachers of broadcasting must constantly reassess their goals and the means to achieve these goals.  相似文献
