pockets. Different programs are provided for those engaged in divers activities. Radio, once a form of group listening that emptied churches, has reverted to private and individual uses since TV The teenager withdraws from the TV group to his private radio. This natural bias of radio to a close tie-in with diversified community groups is best manifested in the disk-jockey cults and in radio's use of the telephone in a glorified form of the old trunkline wire-tapping. Plato, who had old-fashioned tribal ideas of political structure, said that the proper size of a city was indicated by the number of people who could hear the voice of a public speaker. Even the printed book, let alone radio, renders the political assumptions of Plato quite irrelevant for practical purposes. Yet radio, because of its ease of decentralized intimate relation with both private and small communities, could easily implement the Platonic political dream on a world scale. The uniting of radio with phonograph that constitutes the average radio program yields a very special pattern quite superior in power to the combination of radio and telegraph press that yields our news and weather programs. It is curious how much more arresting are the weather reports than the news, on both radio and TV. Is not this because "weather" is now entirely an electronic form of information, whereas news retains much of the pattern of the printed word? It is probably the print and book bias of the BBC and the CBC that renders them so awkward and inhibited in radio and TV presentation. Commercial urgency, rather than artistic insight, fostered by contrast a hectic vivacity in the corresponding American operation.
