On November 2, 1920, KDKA in Pittsburgh signed on as (arguably) the first commercial radio station. They placed a microphone on a table and an announcer read election returns between Warren G. Harding and James Cox that were phoned to him by the Pittsburgh Post. In between updates he played music on a record player set up next to the microphone. Many other people had been broadcasting radio signals as early as 1907, however Westinghouse Corporation was granted the first Broadcast license not issued to a private individual on October 27, 1920, and was assigned the call-letters KDKA. The station has been broadcasting ever since.
So, Happy Birthday Radio!!
