YouTube has just turned eight, and the company is marking the occasion by sharing a couple of cool stats about the service.

Users of the world's most popular video sharing service upload 100 hours of video to the site every minute. That's 6,000 hours of video every hour and a whopping 144,000 hours of video every day.

YouTube also repeated a recently revealed number of one billion visitors to the site per month.

YouTube, which was founded in February 2005 and first launched in May 2005, was acquired by Google in October 2006 for $1.65 billion.

Though the site's growth to one billion users was stunningly fast, Google expects further growth thanks to the rise of mobile devices. Google Executive Chairman Eric Schmidt recently said that number could even grow to 6 or 7 billion.

And if you're wondering where and how Google is storing all those videos, check out this tour through the company's data centers.
