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.
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.
Though he did not say when it would reach that mark, the prediction was not greeted with the skepticism that had met his previous boasts of fast growth.
“They have been more innovative than any other social network, and they are going to continue to grow,” said Jeremiah Owyang, an analyst with the Altimeter Group. “Facebook wants to be ubiquitous, and they are being successful for now.”
The rapid ascent of Facebook has no company more worried than Google , which sees the social networking giant as a threat on multiple fronts. Much of the activity on Facebook is invisible to Google’s search engine, which makes it less useful over time. What’s more, the billions of links posted by users on Facebook have turned the social network into an important driver of users to sites across the Web. That has been Google’s role.
Google has tried time and again to break into social networking not only with Orkut, but also with user profiles, with an industrywide initiative called OpenSocial, and, most recently, with Buzz, a social network that mixes elements of Facebook and Twitter with Gmail. But none of those initiatives have made a dent in Facebook.
Google is said to be trying again with a secret project for a service called Google Me, according to several reports. Google declined to comment for this article.
Google makes its money from advertising, and even here, Facebook poses a challenge.
“There is nothing more threatening to Google than a company that has 500 million subscribers and knows a lot about them and places targeted advertisements in front of them,” said Todd Dagres, a partner at Spark Capital, a venture firm that has invested in Twitter and other social networking companies. “For every second that people are on Facebook and for every ad that Facebook puts in front of their face, it is one less second they are on Google and one less ad that Google puts in front of their face.”
With nearly two-thirds of all Internet users in the United States signed up on Facebook, the company has focused on international expansion.
Just over two years ago, Facebook was available only in English. Still, nearly half of its users were outside the United States, and its presence was particularly strong in Britain, Australia and other English-speaking countries.
The task of expanding the site overseas fell on Javier Olivan, a 33-year-old Spaniard who joined Facebook three years ago, when the site had 30 million users. Mr. Olivan led an innovative effort by Facebook to have its users translate the site into more than 80 languages. Other Web sites and technology companies, notably Mozilla, the maker of Firefox, had used volunteers to translate their sites or programs.
But with 300,000 words on Facebook’s site — not counting material posted by users — the task was immense. Facebook not only encouraged users to translate parts of the site, but also let other users fine-tune those translations or pick among multiple translations. Nearly 300,000 users participated.
“Nobody had done it at the scale that we were doing it,” Mr. Olivan said.
The effort paid off. Now about 70 percent of Facebook’s users are outside the United States. And while the number of users in the United States doubled in the last year, to 123 million, according to comScore, the number more than tripled in Mexico, to 11 million, and it more than quadrupled in Germany, to 19 million.
With every new translation, Facebook pushed into a new country or region, and its spread often mirrored the ties between nations or the movement of people across borders. After becoming popular in Italy, for example, Facebook spread to the Italian-speaking portions of Switzerland. But in German-speaking areas of Switzerland, adoption of Facebook lagged. When Facebook began to gain momentum in Brazil, the activity was most intense in southern parts of the country that border on neighboring Argentina, where Facebook was already popular.
“It’s a mapping of the real world,” Mr. Olivan said.
Facebook is not popular everywhere. The Web site is largely blocked in China. And with fewer than a million users each in Japan, South Korea and Russia, it lags far behind home-grown social networks in those major markets.
Mr. Olivan, who leads a team of just 12 people, hopes to change that. Facebook recently sent some of its best engineers to a new office in Tokyo, where they are working to fine-tune searches so they work with all three Japanese scripts. In South Korea, as well as in Japan, where users post to their social networks on mobile phones more than on PCs, the company is working with network operators to ensure distribution of its service.
Industry insiders say that, most of all, Facebook is benefiting from a cycle where success breeds more success. In particular, its growing revenue, estimated at $1 billion annually, allows the company to invest in improving its product and keep competitors at bay.
“I think that Facebook is winning for two reasons,” said Bing Gordon, a partner at Kleiner Perkins Caufield & Byers and a board member of Zynga, the maker of popular Facebook games like FarmVille and Mafia Wars. Mr. Gordon said that Facebook had hired some of the best engineers in Silicon Valley, and he said that the company’s strategy to create a platform for other software developers had played a critical role.
“They have opened up a platform, and they have the best apps on that platform,” Mr. Gordon said.
With Facebook’s social networking lead growing, it is not clear whether Google, or any other company, will succeed in derailing its march forward.
Says Danny Sullivan, the editor of Search Engine Land, an industry blog, “Google can’t even get to the first base of social networks, which is people interacting with each other, much less to second or third base, which is people interacting with each other through games and applications.”
