Commissioned by Sir Henry Cole (1808-1883), British illustrator John Callcott Horsley (1817-1903) invented the first Christmas card in 1843.
Each year more than 3 billion Christmas cards are sent in the U.S. alone.
In 1962, the first Christmas postage stamp was issued in the United States.
Christmas purchases account for 1/6 of all retail sales in the U.S.
Most of Santa’s reindeer have male-sounding names, such as Blitzen, Comet, and Cupid. However, male reindeer shed their antlers around Christmas, so the reindeer pulling Santa’s sleigh are likely not male, but female or castrati.
