     Facebook, the world's biggest social networking site, is celebrating its sixth birthday. The site's founder, Mark Zuckergerg, states that Facebook will continue to work as hard as it has worked in the last six years in order to stay the web's number one communication site.

     The company started in a dorm room in 2004. Today it has 150 million active users, more than the 130 million of its competitor MySpace.

     Facebook is different from other social networking sites because you can communicate with people you really know and trust. Before, most people didn't want to share their real identities online. Facebook has

given people a safe and trusted environment for people to interact online. It has changed the way people

view the world. A friend from any country is only a few clicks away.

     It was back in February 2004 when Zuckerberg started "the Facebook" from a Harvard student's

room. The aim was to help students get in touch with each other over the Internet. Within 24 hours over a

thousand students had signed up and soon after that the network spread out to other universities.

     By 2005 a research study showed that about 85% of the students in the network had a Facebook

account. Another survey showed that Facebook was almost as important as an iPod. At the end of 2005

Facebook came to the UK. And up to today the site has been translated into 35 languages.

     Six years after its start, Facebook has escaped the universities and colleges. More than half of its users are not at college any more and the fastest growing group are the 30 to 40-year-olds. Every day 15 million users update their profiles to tell their friends and the world what's happening to them. They also share

photos, upload videos, chat, make friends, join groups and simply have fun.
