Election Day in 1920 started it all for the world's first commercial radio station.
On that day, Leo Rosenberg read the evening's results on air in the station's first broadcast.
Rosenberg was the first voice ever heard on the station. He was a member of the Westinghouse publicity department.
Rosenberg voiced a re-creation of the first broadcast during the 1930s, in which they erroneously mentioned the call letters KDKA. The station's identity at the time of the original broadcast was 8ZZ.
