NEW YORK (CNNMoney) -- It's finally happened: Facebook exceeded 1 billion users.
Topping the 1 billion mark means that Facebook now reaches one out of every 7 people on the planet.
While its growth in North America and Europe has leveled off, Facebook continues sucking in new users throughout Asia and the developing world. It has a presence in more than 200 sovereign territories, according to stats tracked by All Facebook, which draws on data Facebook provides to advertisers, and an empire that stretches from a mere 20 users in Vatican City to more than 166 million in the United States.
