Google has launched an extension for Chrome that enables you to follow Santa Claus along his route. You can also use the extension to follow the countdown to his departure, play around with his blimp, elf bus, and write messages on a frosty browser window.
There is a Google Maps Santa Tracker microsite too, where kids can play cool games and know more about Santa.
Efforts like these do two things: keep the magic of Santa Claus & Christmas alive. And build halo around the Google brand. And with kids interacting with Google so early on, it helps carry forward the likeability of brand Google.
