For decades, NORAD has had the inside scoop on track Santa's journey from the North Pole and across the globe.
The North American Aerospace Defense Command, or NORAD, has been tracking Santa's trek since 1955, when a store advertisement misprinted a phone number for a private line to Santa.
NORAD got the calls instead.
As technology has evolved, so has the way kids keep tabs on Mr. Claus.
First phone calls, then the web... now there's NORAD Santa Tracker apps for the iPhone, Android and Windows phone users.
NORAD had been tracking Santa with Google Earth since 2004, but this year, the two entities went separate ways.
Now they've teamed up with Microsoft.
Are you planning to use the NORAD tracker?
