It is ridiculous to broadcast to the masses of a country when the masses are known not to have radio facilities. This was done in the anti-Japanese broadcasts of OWI, at least in the early part of the war, in which mass-audience soap operas and popular music were sent to Japan on the short-wave--this despite reports that short-wave sets were almost unknown outside governmental or plutocratic circles. What was known was that the Japanese government itself had listening facilities, and that the content of American broadcasts was relayed through Japanese military and governmental groups. The propaganda (to fit the medium, radio) should have been designed _to affect the persons actually reached_, and not an audience known to be out of reach. The mere fact that enemy counterpropaganda mentions one's own material is nothing more than a professional exchange of compliments. Goading the enemy radio into a reply may be fun, but unless non-propagandists are known to be listening, the fun is expensive and unprofitable. (It is really fun, though. The author suggested in the spring of 1942 that the San Francisco radio carry an item to the effect that "American art lovers" hoped the Japanese would move their priceless books and paintings away from the great cities. This was preparation for eventual nagging on the topic, "the air raids will get you if you don't watch out!" The radio civilians in San Francisco put the item on the air. Nothing was heard from the Japanese on the subject. Four days later, Radio Luxembourg [then under Nazi control, of course] broadcast in German to Europe that a spokesman for the "beastly American Air Ministry" had told the Japanese that the Americans planned to destroy cultural monuments. The Nazi commentator added that this was characteristic of the actions of uncivilized Americans. New York picked up the German broadcast. The author enjoyed seeing his item go all the way around the world, but in retrospect he wonders whether he did any good other than to please himself. He did do the actual harm of giving the Nazis another point to distort.) _Media_ consist simply of the facilities possessed. These are, most commonly: (1) Standard-wave radio; (2) Short-wave radio; (3) Loudspeakers; (4) Leaflets; (5) Pamphlets; (6) Books; (7) Novelties.
