The American motion picture is the greatest unconscious carrier of propaganda in the world today. It is a great distributor for ideas and opinions. The motion picture can standardize the ideas and habits of a nation. Because pictures are made to meet market demands, they reflect, emphasize and even exaggerate broad popular tendencies, rather than stimulate new ideas and opinions. The motion picture avails itself only of ideas and facts which are in vogue. As the newspaper seeks to purvey news, it seeks to purvey entertainment.
Mass production is only profitable if its rhythm can be maintained.. that is, if it can continue to sell its product in steady or increasing quantity. The result is that while, under the handicraft or small-unit system of production that was typical a century ago, demand created the supply, today supply must actively seek to create its corresponding demand.
