In 1955, a Colorado Springs-based Sears store ran an advertisement encouraging children to call Santa Claus on a special telephone hotline. Due to a printing error, the phone number that was printed was the hotline for the Director of Operations at the Continental Air Defense (CONAD). Colonel Harry Shoup took the first Santa call on Christmas Eve of 1955 from a six-year old boy who began reciting his Christmas list. Shoup didn't find the call funny, but after asking the mother of the second caller what was happening, then realizing the mistake that occurred, he instructed his staff to give Santa's position to any child who called in.
And now, with the magic of Google Earth, you too can track Santa in real time.
