1920: KDKA Pittsburgh becomes first radio station in US
On November 2, 1920, KDKA became the first American radio station when it aired the results of the 1920 presidential election.
By broadcasting the results, “the power of radio was proven when people could hear the results of the Harding-Cox presidential race before they read about it in the newspaper,” according to PBS.
Dozens of other stations began to pop up across the US following the success of KDKA’s broadcast, giving advertisers a new way to reach consumers.
