Facebook hits billion users in a day

For the first time over a billion people used Facebook on a single day, according to company founder Mark Zuckerberg.

The "milestone" was reached 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 March this year, Facebook employees moved into their new Frank Gehry-designed Silicon Valley headquarters in California – a 40,000-square-metre office building with "the largest open floor plan in the world" and a huge rooftop park.
