abstract = "Popular film was a most important twentieth century commodity. It is worthy of study by the economic historian, not because it employed many people, which it did not, or because it contributed greatly to national income, which it did not, but because it attracted extremely large numbers of consumers to spend time voluntarily, in preference to other activities, experiencing some measure of well-being derived from sequences of moving images and their associated aesthetics.",
