For years, well, since 1955, NORAD has been tracking the progress of Santa on Christmas. It started by accident; that year, a Sears advertisement told kids to call to talk with Santa, but because of a typo, the kids' calls went to the Commander-in-Chief of what was soon to be NORAD instead. Playing along, NORAD began to track Santa on their radars, updating kids with St. Nick's progress throughout the night.
Lately, Google's been in on the festivities, tracking the Jolly One on Google Earth and Google Maps. This year, Santa gets into social networking in a big way. Go to m.noradsanta.org on your mobile phone, or just pick your favorite: Facebook or Twitter. You can also check out his gallery on Picasa.
Who knew Santa was so cool? I'll bet Rudolph knew.
