SAN FRANCISCO, Feb 7 (Reuters) - Facebook.com has introduced a version of the site for Spanish-language speakers, the first of several languages beyond English the social network site plans to offer, the company said on Thursday.

Facebook, an online social network that has enjoyed explosive international growth over the past nine months despite remaining an English-only site, said it will introduce German and French versions within weeks.

Sixty percent of Facebook's roughly 64 million users live outside of the United States. More than 2.8 million active users live in Latin America or Spain, the company said.

The Silicon Valley-based company was founded in 2004 as a social site for students at Harvard University and spread quickly to other colleges and eventually into workplaces. Its popularity stems from how the site conveniently allows users to share details of their lives with selected friends online.

Facebook users can choose to view the site in Spanish by changing their account settings. Starting on Monday, Facebook users who sign on to the Web from Spanish-speaking countries will automatically be directed to Facebook en espanol.

As part of the internationalization project, translated versions of the site will be available to Facebook fans on both computers and mobile phones.

Facebook is playing catch-up on the international front to rival News Corp's (NWSa.N: Quote, Profile, Research, Stock Buzz) MySpace, which has national sites in more than 20 countries. MySpace offers versions of its site in Spanish, French, German and Italian, including a site for U.S. Spanish speakers and another for French Canadians.
