"The radio is a new force in the life of Middletown, second only to the automobile in its potential for reshaping the habits of its citizens. In 1920, there were no radios; by 1924, hundreds of antennas spanned the town's rooftops. Yet, while the radio brings the world to the home, it also introduces a standardization of entertainment that threatens the distinctiveness of local traditions, as families sit silently listening to the same jazz orchestra in New York or the same political speech in Washington."
—Adapted from Robert S. Lynd and Helen Merrell Lynd, *Middletown: A Study in Modern American Culture*, 1929
