On this day in 1920 the World's First Broadcast by a commercially licensed radio station happened when KDKA Pittsburgh, Pennsylvania broadcast the Harding-Cox Presidential Election Returns. Announcer Leo Rosenberg delivered the results starting at 6:00pm.

However, this fact is contested by media historians, who note that 8MK in Detroit (later WWJ) was on the air doing regular broadcasts in late August 1920. Further, there was no commercial license till mid-1921 and the first station to receive one was WBZ, which was then located in Springfield Massachusetts.

None the less, this is the date in which Radio as we know it today is celebrated.

Perhaps, that is the answer: KDKA had those call letters at that time. The other stations like the ones in Detroit and San Francisco(KCBS, dating back to 1909)were still experimental and had experimental calls.

Birthday? Let the spanking begin!

OH MY Val....
