Maggie's Notebook, you can read about the history of NORAD [North American Aerospace Defense Command] that has been continuous since 1955, when CONAD (later renamed NORAD) began receiving phone calls from children to relay their Christmas wish list.
NORAD official site.
Every year they ask for volunteers to perform traditional duties at NORAD for Santa Claus, who has his own website.
Ho! Ho! Ho! Merry Christmas to All.
