|One of the earliest photographs (circa 1921) of the broadcasting studio of KDKA-AM radio in Pittsburgh (original studio located at the Westinghouse plant in East Pittsburgh). KDKA was the world's first commercial broadcasting station, beginning with its first broadcast: the Harding-Cox U.S. Presidential Election Returns, which commenced at 6:00 p.m. EST / 23:00 UTC on Tuesday, 1920 November 2. Today, KDKA, which now broadcasts 50,000 watts of transmission power on AM 1020, can be heard on the radio at night in 38 states and half of Canada, as well as everywhere, anytime at http://kdkaradio.com.
