Facebook, the social network service that started in a Harvard dorm room just six years ago, is growing at a dizzying rate around the globe, surging to nearly 500 million users, from 200 million users just 15 months ago.
It is pulling even with Orkut in India, where only a year ago, Orkut was more than twice as large as Facebook. In the last year, Facebook has grown eightfold, to eight million users, in Brazil, where Orkut has 28 million.
In country after country, Facebook is cementing itself as the leader and often displacing other social networks, much as it outflanked MySpace in the United States. In Britain, for example, Facebook made the formerly popular Bebo all but irrelevant, forcing AOL to sell the site at a huge loss two years after it bought it for $850 million. In Germany, Facebook surpassed StudiVZ, which until February was the dominant social network there.
With his typical self-confidence, Mark Zuckerberg, Facebook’s 26-year-old chief executive, recently said it was “almost guaranteed” that the company would reach a billion users.
