For about a century, Western culture has really been two cultures: the traditional kind—let us call it ‘High Culture’—that is chronicled in the textbooks, and a ‘Mass Culture’ manufactured wholesale for the market. In the old art forms, the artisans of Mass Culture have long been at work: in the novel, the line stretches from Eugène Süe to Lloyd C. Douglas; in music, from Offenbach to tin-pan alley; in art, from the chromo to Maxfield Parrish and Norman Rockwell; in architecture, from Victorian Gothic to suburban Tudor. Mass Culture has also developed new media of its own, into which the serious artist rarely ventures: radio, the movies, comic books, detective stories, science-fiction, television.
