1921: Christmas Takes the Radio
Many of today's traditions began during Prohibition-era America. With the ubiquity of the radio by this time, the recent invention had become the most popular gift and also the center of most social gatherings—particularly for live-broadcasted holiday concerts.
Radios were globally influential, and in 1922, the BBC started daily programs. The BBC broadcasted its first orchestral concert on December 23 and its first radio-broadcasted play, "The Truth About Father Christmas," on December 24.
