Facebook is the second largest social network on the web, behind only MySpace in terms of traffic. Primarily focused on high school to college students, Facebook has been gaining market share, and more significantly a supportive user base. Since their launch in February 2004, they’ve been able to obtain over 8 million users in the U.S. alone and expand worldwide to 7 other English-speaking countries, with more to follow. A growing phenomenon, let’s discover Facebook.

In 2007, the website has the largest number of registered users among college-focused sites, with 55 million active members (including non-collegiate members) worldwide, with membership expected to surpass 60 million users by the end of the year. From September 2006 to September 2007 the site's traffic ranking increased from 60th to 7th, according to Alexa. It is the number one site for photos in the United States, ahead of public sites such as Flickr, with over 60 million photos uploaded weekly.

The name of the site refers to the paper facebooks depicting members of the campus community that some U.S. colleges and preparatory schools give to incoming students, faculty, and staff as a way to get to know other people on campus.

Facebook is a massively successful social networking service that grew to prominence in virtually no time. It’s not hard to see why: its features and tools are highly appealing, and Facebook users are extremely well networked in real life. Rumors of an acquisition continue to circulate, with some estimates putting the price in the billions of dollars. In the short term, however, Facebook plans to go it alone, continuing to build out one of the world’s most successful social networks.
