NORAD began to track Santa Claus in 1955, following an accidental phone call made to the agency by a young boy interested in in speaking with Kris Kringle.

NORAD is the most reliable name in Santa tracking. On the job since 1955, when a young child from Colorado Springs accidentally called in (he meant to call a number advertised by a local department store), they've been following Santa's journey using their radar technology ever since.
