Facebook is an American online social media and social networking service. The Facebook website was launched on February 4, 2004, by Mark Zuckerberg, along with fellow Harvard College students and roommates.
The founders had limited the website's membership to Harvard students at first; however, later they expanded it to various other universities, and eventually to high school students as well. Since 2006, anyone who claims to be at least 13 years old has been allowed to become a registered (注册了的) user of Facebook, though differences exist in the youngest age requirement, depending on local laws. Facebook has more than 2 billion monthly active users as of June 2017. As of April 2016, Facebook was the most popular social networking site in the world, based on the number of active user accounts.
Facebook may be accessed by a large range of desktops, smartphones over the Internet and mobile networks. After registering to use the site, users can create a user profile (简介) showing their names and so on. Users can add other users as "friends", exchange messages, post photos and so on.
Facebook makes most of its income from advertisements which appear on screen, marketing access for its customers to its users.
