A Facebook page is a public profile specifically created for businesses, brands, celebrities, causes, and other organizations. Unlike personal profiles, pages do not gain "friends," but "fans" - which are people who choose to "like" a page. Pages can gain an unlimited number of fans, differing from personal profiles, which has had a 5,000 friend maximum put on it by Facebook. Pages work similarly to profiles, updating users with things such as statuses, links, events, photos and videos. This information appears on the page itself, as well as in its fans' personal news feeds.
