For the first time over a billion people used Facebook on a single day, according to company founder Mark Zuckerberg.
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.
It was founded in 2004 by Mark 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.
