Over the years, there have been a number of websites created by various organizations that have purported to track Santa. Some, such as NORAD Tracks Santa, the Airservices Australia Tracks Santa Project, the Santa Update Project, and the MSNBC and Bing Maps Platform Tracks Santa Project have endured. Others, such as the Dallas/Fort Worth International Airport's Tracks Santa Project, the Santa Retro Radar – Lehigh Valley Project, and the NASA Tracks Santa Project, have fallen out of use.
