During the 1920s, many Americans had extra money to spend, and they spent it on consumer goods such as ready-to-wear clothes and home appliances like electric refrigerators. In particular, they bought radios. The first commercial radio station in the U.S., Pittsburgh’s KDKA, hit the airwaves in 1920; three years later there were more than 500 stations in the nation. By the end of the 1920s, there were radios in more than 12 million households. People also went to the movies: Historians estimate that, by the end of the decades, three-quarters of the American population visited a movie theater every week.
But the most important consumer product of the 1920s was the automobile. Low prices (the Ford Model T cost just $260 in 1924) and generous credit made cars affordable luxuries at the beginning of the decade; by the end, they were practically necessities. In 1929 there was one car on the road for every five Americans. Meanwhile, an economy of automobiles was born: Businesses like service stations and motels sprang up to meet drivers’ needs.
