Chrome is one of Google’s biggest success stories. Rank it up there with search that doesn’t suck (hard to find back in the day) and AdWords (the print-your-own money machine that drives everything else Google does).

Today at Google I/O Sundar Picahi, senior VP of Chrome and apps, says that Chrome is not only the most popular browser in the world, it’s now in active use by 310 million people.

That’s double last year’s numbers and astonishing growth, pushing past Microsoft’s Internet Explorer earlier this year.
