Facebook has reached the 1 billion user mark — people who are "actively" using the social network every month — the company announced today.
Mark Zuckerberg introducing Timeline at last fall's F8.
"If you're reading this: thank you for giving me and my little team the honour of serving you. Helping a billion people connect is amazing, humbling and by far the thing I am most proud of in my life," CEO Mark Zuckerberg said on Facebook's online newsroom
The social network, which started in a dorm room in 2004, reached the historic milestone at 12.45pm PT on 14 September. This now puts one in seven people around the world on the social network.
Zuckerberg also announced the milestone on NBC's Today show. The milestone does not include bots or fake users, but real people with accounts who log in to the site every month, NBC reported.
If Facebook were a country, it would be the third largest in the world, behind China with 1.34 billion people and India with 1.2 billion.
Since launching eight years ago, according to Facebook, the site has seen:
1.13 trillion "likes"
140.3 billion friend connections
219 billion photos uploaded (265 billion in all, if deleted photos are counted)
17 billion location check-ins
62.6 million songs played 22 billion times since September 2011.
The median age of users is 22 years old, Facebook said. When the social network hit 500 million users in July 2010, the median age was 23. People who joined in July 2010 now have an average of 305 friends.
The company also has more than 600 million mobile users — up by 48 million from 552 million in June — a key metric for those in developing nations who may not have stable access to a fixed-line internet connection.
