In the early 20th century, a revolutionary new technology emerged: the radio. Initially, people used the radio for military communications during World War I. However, by the 1920s, it had transitioned into a popular medium for entertainment and news dissemination. The radio allowed families to gather around their sets to listen to music, drama, and news broadcasts, creating shared experiences in homes across America. This technology not only transformed the way information was disseminated but also had a profound effect on culture, contributing to the rise of mass entertainment.
By the end of the 1930s, the radio had solidified its role as a staple in American life, influencing public opinion and becoming a key player in political campaigns.
