6(4). Mass Production: Media, Radio, etc.

New technology led to the spread of culture and media in the interwar years. The first significant technology was the radio in the late nineteenth century, although the first transmission to a large audience was not until 1920. This allowed many people to listen to the same thing at the same time. By the 1930's, millions of radios had been sold to citizens of all countries. Another new technology was the invention of cinema which allowed people to watch movies.
