Overview: "Cosmopolis: 1914-1931" recalls the WWI years and the "Roaring '20s" in the city that F. Scott Fitzgerald called "the land of ambition and success." Of course, an egg was laid on Wall Street in 1929, but before that happened the city gave rise, narrator David Ogden Stiers says, "to a new culture, a mass culture" that was broadcast live on radio networks headquartered in New York.
