This year, NORAD is teaming up with Alexa to help track Santa’s whereabouts.

Alexa will be using the military-run program tracking his route. The public can ask Alexa “Where’s Santa?” and Amazon’s voice-activated computer service will answer.

The tracking service began in 1955 when a newspaper ad invited children to call Santa but mistakenly ran the phone number for the hotline for NORAD’s predecessor, the Continental Air Defense Command.
