So with the manuscript before typography, since manuscript culture is oral and demands dialogue and debate, as the entire culture of the ancient and medieval worlds demonstrates. One of the major pressures of TV has been to encourage the "teaching machine." In fact, these devices are adaptations of the book in the direction of dialogue. These teaching machines are really private tutors, and their being misnamed on the principle that produced the names "wireless" and "horseless carriage" is another instance in that long list that illustrates how every innovation must pass through a primary phase in which the new effect is secured by the old method, amplified or modified by some new feature. Film is not really a single medium like song or the written word, but a collective art form with different individuals directing color, lighting, sound, acting, speaking. The press, radio and TV, and the comics are also art forms dependent upon entire teams and hierarchies of skill in corporate action. Prior to the movies, the most obvious example of such corporate artistic action had occurred early in the industrialized world, with the large new symphony orchestras of the nineteenth century. Paradoxically, as industry went its ever more specialized fragmented course, it demanded more and more teamwork in sales and supplies. The symphony orchestra became a major expression of the ensuing power of such coordinated effort, though for the players themselves this effect was lost, both in the symphony and in industry. When the magazine editors recently introduced film scenario procedures to the constructing of idea articles, the idea article supplanted the short story. The film is the rival of the book in that sense. (TV in turn is the rival of the magazine because of its mosaic power.) Ideas presented as a sequence of shots or
