LOUISVILLE, Ky. (WDRB) -- Santa was a pretty popular guy online.

The North American Aerospace Defense Command (NORAD) says it had over 19.5 million hits on its Web site Christmas Eve to track Santa.

Volunteers also answered over 117,000 phone calls for kids asking his whereabouts. Hundreds of thousands of others tracked Santa on Twitter and Facebook.

The Christmas tradition of tracking Santa began in 1955, when a local newspaper advertisement invited children to call Santa, but mistakenly listed the hotline of NORAD's predecessor.
