 Happy Holidays! Santa has completed his journey around the world and is taking a much deserved break. Visit us again next year! ||||| After five years of working with Google, NORAD has switched to Microsoft Bing to track Santa's sleigh ride this Christmas Eve. 
 
 That hasn't stopped Google from continuing to monitor Santa on its own. 
 
 NORAD, or the North American Aerospace Defense Command, thinks it has the most sophisticated system for watching the Big Guy. It uses "four high-tech systems to track Santa—radar, satellites, Santa Cams and fighter jets." 
 
 NORAD has been tracking Santa for 62 years, long before the introduction of Google Maps, Bing Maps, or the Internet, for that matter. 
 
 It's a pretty serious endeavor, too. 25 million people will use NORAD's Santa-tracking site this year, which will run on Microsoft's Windows Azure cloud-computing platform and Bing Maps, reports Sharon Gaudin on Computerworld. 
 
 NORAD is also offering Windows 8, Windows Phone 8, and Android Santa-tracking apps. 
 
 NORAD's Lt. Cmdr. Bill Lewis says it isn't leaving Google because of any problems. 
 
 "It was a mutually agreed-upon split," Gaudin reports. 
 
 Google isn't hopping off the Santa sleigh ride, according to a blog post by Brian McClendon, VP of Google Maps and Google Earth. 
 
 "While we’ve been tracking Santa since 2004 with Google Earth, this year a team of dedicated Google Maps engineers built a new route algorithm to chart Santa’s journey around the world on Christmas Eve. On his sleigh, arguably the fastest airborne vehicle in the world, Santa whips from city to city delivering presents to millions of homes." 
 
 NORAD will begin tracking Santa at 2 a.m. Eastern Time on Dec. 24, via the new apps, its website, or email sent to noradtrackssanta@outlook.com. (Outlook.com is another Microsoft product.) People can also call the official Santa tracking phone number, 1-877-Hi-NORAD (1-877-446-6723) for live updates. 
 
 Google will begin tracking Santa at 2:00 a.m. Pacific Time on Dec. 24, via its Santa Tracker website, a new Chrome extension or an Android app and its Google+, Facebook, and Twitter pages. 
 
 Don't miss: Guess When These 20 Sci-Fi Technologies Are Coming To Your Phone Or PC ||||| It could be the most controversial technological break-up since Apple ditched Google maps for its own inferior version. 
 
 On Wednesday, the North American Aeropsace Defense Command (Norad), announced that it has teamed up with Microsoft Bing to power its annual "Santa tracker" after its previous partner, Google, announced it was launching its own version. 
 
 Norad, which usually spends its time monitoring the air space above the US and Canada for unexplained or criminal aerospace activity, has "tracked" the worldwide progress of Santa's gift-giving journeys at Christmas since 1955. For the past five years, it used Google Maps to display its "data", which is hugely popular with children. 
 
 Norad said the split from Google Maps, who it had worked with to track Santa since 2007, was a mutual decision. 
 
 Google now has its own virtual Santa space , which features an animated interactive tour of Santa's village, including games and a service to offer personalized telephone calls from Santa to children. 
 
 In response, Norad signed up Bing to be its official mapping tool. Microsoft joins 51 other organizations who work offer their services pro-bono to Norad for the agency's more than 60-year-old tradition. 
 
 Norad's tracking feature will also include information about the elevation and direction of Santa's "journey" and photos, weather and Wikipedia information on the destinations. 
 
 Before working with Norad, Google tracked Santa using its Google Earth tool. The company will still be loosely affiliated with Norad as Google-owned YouTube will continue to host dispatches from the government agency concerning Santa's whereabouts. 
 
 Updates from Norad on the Christmas journey will also be available on Twitter, Facebook and by placing calls to the agency's Santa tracking phone line 877 HI-NORAD. 
 
 Norad, and its predecessor the Continental Air Defense Command (Conad), have been tracking Santa since 1955. It started when a department store ad accidentally listed the agency's phone number as a way to follow Santa. A Norad worker who answered a call from a child wondering about Santa's whereabouts decided to follow the ruse and the agency has been involved with the tradition ever since. 
 
 More than 1,250 Canadian and Americans volunteer on Christmas eve to maintain the tradition. 
 
 There's no word yet on whether the switch from Google to Bing's mapping service will likely help or hinder Santa's progress.
– After five years of tracking Saint Nick, Google and NORAD are going their separate ways. The North American Aerospace Defense Command announced this week that it was now working with Microsoft Bing to follow Santa's worldwide progress, the Guardian reports. Google has launched its own "Santa tracker" including games and personalized calls from Saint Nick to children. But NORAD's tracking system will be no slouch, with data on Santa's elevation, photos of his journey, weather, and Wikipedia information on his various stops. And NORAD will offer updates on Santa's trip via Twitter and YouTube. Twenty-five million people will likely use NORAD's tracker this year via Bing Maps and apps for Windows 8, Windows Phones, and Android phones, reports Business Insider. NORAD began tracking Santa when a misprint in a 1955 department store ad led a child to call the agency for information on Santa's latest stop. The NORAD employee who took the call made sure to answer, and the agency has maintained the tradition ever since.
