If you want to keep an eye on Santa this Christmas Eve, there's an app for that. NORAD has been tracking the St. Nick's trip around the world for years and they're expecting thousands of phone calls (877-HI NORAD) and emails this year.

But that's not the only way to watch St. Nick. You can "like" NORAD Tracks Santa on Facebook, follow the Santa tracker on Twitter, watch videos on YouTube, or download the app for iPhone and Android.
