Until television-in-color, which exists, becomes common, the need for this new language is great. For neither the movies nor radio can be used for reasoned persuasion; their attack is too immediate, the listener-spectator does not have time for argument and contemplation. Radio profits positively by its limitation to sound when it works with the right materials; but when President Roosevelt asked his audience to have a map at hand, television supplied the map and the meaning of the map without diverting attention from the speech, which radio could not do. The movies, great pioneer in text and sound, have mastered none of the arts of demonstration or persuasion; they have the immediate gain of a single method and a single objective: appeal to the emotions by absorption in the visual; and the fact that the moving picture's appeal is to a group, means that every element must be over-simplified and every effect is over-multiplied by the group presence. By this the movies also gain when they use the right materials. The use of the new combination of text and image, growing out of the tabloid and the picture magazine, is, in effect, the creation of a mobile reserve of propaganda. When the radio and the movies have established the facts and aroused the desired emotion, the final battery of argument comes in picture and print; and this, ideally, is carried to the ward meeting, to the after-supper visit, the drugstore soda counter and the lunch hour at the factory--where the action is determined by men and women in private discussion. _Universal Languages_ Radio, which instantly creates the desired situation, and movies, which so plausibly arouse the desired emotion, are the two great mass inventions of America. The patents may have been taken out elsewhere, but it was in America that these two forms of mass communication were instantly placed at the service of all people. The errors of judgment have been gross, but the error of purpose was not made; the movies were kept out of the hands of the aesthete and radio was kept out of the hands of the bureaucrat. For a generation we deplored the vulgarity of movies made for morons' money at the box office, and discovered that the only other effective movies were made by dictators, to falsify history, as the Russians did when the miserable Trotsky was cinematically liquidated, or to stir hate as did every film made by Hitler. For a generation we wept over the commercialism of radio and at the end found that commercial radio had created an audience for statesmen and philosophers; and again the alternative was the hammering of dictators' propaganda, to which one listened under compulsion.
