Eventually Facebooks reaches a billion users in a day :)

Mark Zuckerberg Says on his post, "We made this video to celebrate all you've done to help our community connect one billion people in a single day. It's an amazing milestone. I hope you enjoy."
"A more open and connected world is a better world. It brings stronger relationships with those you love, a stronger economy with more opportunities, and a stronger society that reflects all of our values," he said.

The "milestone" was reached on Monday, when "1 in 7 people on Earth used Facebook to connect with their friends and family", he said in a post. Facebook has nearly 1.5 billion users who log in at least once a month, but this was the most in a single day. The company gained its billionth user in October 2012. It was founded in 2004 by Mr Zuckerberg while he was a Harvard student. In his post on Thursday, he predicted that Facebook's reach would continue to grow.

"This was the first time we reached this milestone, and it's just the beginning of connecting the whole world," Mr Zuckerberg wrote. In July, Facebook claimed that over half of the world's online users visited the site at least once a month.

Zuckerberg posted a video dedicated to the achievement. See here Billion Users Special Video
