Sergey Brin, a Google founder, takes issue with people who say Google has failed to gain a foothold in social networking. Google has had successes, he often says, especially with Orkut, the dominant service in Brazil and India.
Mr. Brin may soon have to revise his answer.
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.
