This is a study of the working processes of the American system of radio broadcasting as envisaged by the Federal Radio Act of 1927 and the Federal Communications Act of 1934. It aims to show in what respect the censorship provisions of the Philippine law on radio broadcasting violates freedom of speech as guaranteed in the Constitution of the Philippines; and to select among the possible types of censorship or regulatory control over the broadcast programs of radio stations. The author also attempted to point out in what manner and to what extent the Philippine may, by legislation, work out an improvement along democratic lines upon the scope of controversial discussion as practiced in the United States by extending the subjects thereby covered.
