1 billion people used Facebook in 24 hours

For the first time ever, a mind-boggling 1 billion people used Facebook in one day this Monday.

CEO Mark Zuckerberg revealed the milestone in a Facebook post Thursday afternoon, pointing out that number is the equivalent of one in seven people on Earth who signed on to check out the social network over the course of 24 hours.

“When we talk about our financials, we use average numbers, but this is different,” Zuckerberg wrote. “This was the first time we reached this milestone, and it’s just the beginning of connecting the whole world.”

Since Zuckerberg created Facebook in his Harvard dorm room in 2004, the social network has become the second most-trafficked website in the U.S. and worldwide. The social network currently reports 1.49 billion monthly active users, which means that about 2/3 of its entire userbase logged on some time Monday. That’s pretty darned impressive, whether you like Facebook or not.
