NORAD, and it's predecessor
CONAD, have been tracking the progress of Santa on Christmas Eve since 1955. NORAD
has a website for kids to follow the progress of Santa and has the full
history of this operation.
The tradition began after a Colorado Springs-based Sears Roebuck & Co. store advertisement for children to call Santa on a special "hotline" included an inadvertently misprinted telephone number. Instead of Santa, the phone number put kids through to the CONAD Commander-in-Chief's operations "hotline." The Director of Operations, Colonel Harry Shoup, received the first "Santa" call on Christmas Eve 1955. Realizing what had happened, Colonel Shoup had his staff check radar data to see if there was any indication of Santa making his way south from the North Pole. Indeed there were signs of Santa and children who called were given an update on Santa's position.
