Santa Claus
In the past, many local television stations in the United States and Canada likewise claimed they tracked Santa in their own metropolitan areas through the stations' meteorologists. In December 2000, the Weather Channel built upon these local efforts to provide a national Christmas Eve Santa tracking effort called SantaWatch in cooperation with NASA, the International Space Station, and Silicon Valley-based new multimedia firm Dreamtime Holdings. In the 21st century, most local television stations in the United States and Canada rely upon outside established "Santa tracking" efforts, such as NORAD Tracks Santa.
