Unless you’re slightly doolally, you’ll know that today is Christmas Eve, the day before Christmas. Tonight is the night when Santa Claus earns his crust by delivering presents to everyone on his list.

Thanks to Norad (North American Aerospace Defense Command) we can now all track Santa’s progress as he makes his deliveries around the world. And all from the comfort of our own living rooms.

The Norad Santa Tracker detects Santa leaving the North Pole and then tracks him all night as he arrives at every country around the world in turn. Kids now know when they need to be asleep by.

Back in my day, I had to believe in Santa Claus purely based on what adults were telling me. Now, children can see Santa for themselves. And all thanks to the power of technology, and a by-product of the nuclear arms race.
