Google is now officially an adult. The internet giant is celebrating its 18th birthday on Tuesday with an animated Doodle shown to web browsers around the world.
The company, founded by Larry Page and Sergey Brin in 1998, traditionally marks its birthday on the Google homepage on September 27.
However, not even Google seems to really know when it was formed. Since 2006, it has celebrated its birthday on September 27, but the year before that, had it as September 26.
