History of Commercial Radio from the Federal Communications Commission (FCC)November 2, 2020, marks the 100th anniversary of what is widely recognized as the first commercial radio broadcast when Westinghouse Electric and Manufacturing Company in Pittsburgh, under the call sign KDKA, broadcast the live returns of the Harding-Cox presidential election.
Over the last century, radio transformed from a cumbersome, experimental medium to a mobile, modern format that ushered in new technologies like television and cellular telephones. Within just four years of the initial KDKA broadcast, 600 stations existed in the U.S. and radio’s rapid popularity contributed to our shared national identity by providing syndicated news, sports, and music. For many, radio was the fastest reliable way to receive updates about national and world events.
