Why did they name Facebook Facebook?

Hey dude, at first, facebook is just a blog site created by mark zuckerberg for their university to have an access to everyone, for their projects, miscellaneous, private talks, group chats, etc.. But one day, a friend of him asked him, " Why you no make it open for everyone?", mark think about it, and he release facebook as a social site wherein you can have friends, have a conversations with them, see their photos, etc. Hope this may be helpful

It used to be a paper-based document to orient new University students including a page of identity photos of other students on their courses (known as a "face" book).
