Children (of all shapes, sizes and ages) are again tracking that jolly old elf via the North American Aerospace Defense Command, aka NORAD, with a holiday tradition that dates back to 1955. History tells us that the whole thing started by accident. It turns out that a Colorado department store placed an ad in the local paper for its own Santa hotline, but instead, the number was a misprint, directing phone calls to the regional headquarters of the then-Continental Air Defense Command (which later became NORAD).
This year, NORAD has a pretty sophisticated "tracker" showing Santa's exact trajectory, where he was last seen (as of 9:30 a.m., Mountain time, he was heading west, toward Novosibirsk, Russia). It also shows how many gifts have been delivered (nearly 1.7 billion and counting).
All in, it's not a bad distraction to show the kids who are practically jumping out of their skin waiting for their own visit tonight.
