Facebook
Facebook is a social networking service launched in February 2004. Facebook has over one billion active users. They may create a personal profile, add other users as friends, and exchange messages. Additionally, users may join common-interest user groups, organized by workplace, school or college, or other characteristics, and categorize their friends into lists such as "People From Work" or “Best Friends".
Facebook was founded by Mark Zuckerberg with his college roommates and fellow Harvard University students. The website's membership was initially limited by the founders to Harvard students, but was expanded to other colleges in the Boston area, the Ivy League, and Stanford University. It gradually added support for students at various other universities before opening to high school students, and eventually to anyone aged 13 and over.
