Radio is used in foreign countries for recreation and music, Schools, Police, Business, Municipalities, Agriculture, Trains, hospitals and prisons etc. Nothing need be said about radio for recreation as it has become a necessary furniture in every household in foreign countries. School radio was a recent introduction for supplementing education taught by the average teacher in the schools. Radio for the use of Police has become almost indispensable in detecting criminals and evil-doers. For businessmen, broadcasting is in many countries a means of effective advertisement. For the press it is readily a source of news and for the seaman it is really a weather prophet. Broadcasting has already become indelibly interwoven into every branch of industry.
