For those of you who have followed Santa's trip in Google Earth for the past few years, you'll be interested to know that this year we've paired up with the real Santa-tracking pros -- the North American Aerospace Defense Command (NORAD).

Starting tomorrow, December 1st, you'll be able to count down to the big sleigh ride on the NORAD Tracks Santa website; starting at 1 am PST on December 24th, you'll be able to download a special KML file that lets you follow his trip in real time. Check out the Official Google Blog to learn more about our involvement in this Santa-tracking tradition that began more than 50 years ago.
