In 1955 the Sears Roebuck and Co shop based in Colarado Springs advertised a ‘Santa Hotline‘ with a telephone number for children to call and talk to him. Unfortunately they included the telephone number not of their store but of the Commander in Chief of the Continental Air Defense Command (CoNAD). Rather than disappoint the children that were calling to speak to Santa, the military men and women gave them the location of Santa as they tracked his progress on their radar. They have done it ever since. Of course it is now much more than just a radar track and you can follow his progress via google maps. The site has lots of games based around Santa’s trip. The whole thing is now manned by volunteers and funded by contributions from businesses and individuals.
