The first radio broadcasts were used to relate the election results of the 1920 Presidential Election. By 1925, there were 600 radio stations across the United States. By 1923, nearly three million Americans had radios. Music, stories, sporting events, and news were soon being broadcast nationwide. A stronger national, rather than regional, identity emerged in the United States.
Radio helped to create a common cultural experience for thousands of Americans. Advertisers were quick to realize the marketing potential of radio. They began using radio to mass market the multitude of consumer goods that were developed in the period, such as washing machines, electric toasters, and laundry soap. Products and brands were becoming more widespread due to the vast market radio offered.
