“Whatever the box-office blips, the regular movie audience has been so decimated over the past 56 years that the habitual weekly adult moviegoer will soon qualify as an endangered species. In 1948, 90 million Americans—65 percent of the population—went to a movie house in an average week; in 2004, 30 million Americans—roughly 10 percent of the population—went to see a movie in an average week. What changed in the interval was that virtually every American family bought a TV set, and home entertainment largely replaced theater entertainment. More important than mere numbers, the nature of the audience changed in this secular decline.”
