From NORAD's website:
PETERSON AIR FORCE BASE, Colo. -- The North American Aerospace Defense Command is getting ready to track Santa’s yuletide journey! The NORAD Tracks Santa website, www.noradsanta.org, went live today featuring a Countdown Calendar, a Kid’s Countdown Village complete with holiday games and activities that change daily, and video messages from students and troops from around the world. With the addition of Brazilian Portuguese, the website is now available in eight languages: English, French, Spanish, German, Italian, Japanese, Brazilian Portuguese, and Chinese.
Starting at midnight MST on Dec. 24, website visitors can watch Santa as he makes all the preparations for his flight. Then, at 4 a.m. MST (6 a.m. EST), trackers worldwide can talk to a live phone operator to inquire about Santa’s whereabouts by dialing the toll-free number 1-877-Hi-NORAD (1-877-446-6723) or by sending an email to firstname.lastname@example.org. NORAD’s “Santa Cams” will also stream videos as Santa makes his way over various locations worldwide.
NORAD Tracks Santa has truly become a global experience, delighting generations of families everywhere. It is due, in large part, to the efforts and services of numerous contributors. New to this year’s program are Acuity Scheduling, Big Fish Worldwide, Carousel Industries, the Colorado Springs Chamber of Commerce Military Affairs Council, General Electric, the National Tree Lighting Ceremony, RadiantBlue Technologies Inc., thunderbaby studios, the U.S. Coast Guard Band, the U.S. Merchant Marine Academy Band, Visionbox, and the West Point Band.

It all started in 1955 when a local media ad directed kids to call Santa direct – only the number was misprinted. Instead of reaching Santa, the phone rang through to the Crew Commander on duty at the Continental Air Defense Command Operations Center. Thus began the tradition which NORAD has carried on since it was created in 1958.
“NORAD stands the watch protecting the skies of North America 365 days a year, but on Christmas Eve the children of the world look to NORAD, and our trusted partners, to make sure that Santa is able to complete his mission safely,” said General Charles H. Jacoby, Jr., NORAD Commander.
“This mission is a duty to the children of the world and a privilege we've enjoyed for 56 consecutive years, but the effort could not be carried out without the superb assistance of numerous government and non-government contributors. It is the generosity of these contributors, the hard work of the more than 1,200 volunteers who man the NORAD Tracks Santa Operation Center, and vigilance of the Canadian and U.S. forces who work at NORAD that guarantees the program's success each and every year."
BTW: This is based on Google Earth. If you press the plus sign, you can zoom in close enough to see buildings and such, and maybe catch Santa actually going down a chimney
