Facebook can be literally translated as “book of faces”, where “face” is the guy (or guys) and “book” is the book.
Facebook is the most popular social network in Brazil, having been established in 2004. Its founders, Mark Zuckerberg, Eduardo Saverin, Andrew McCollum, Dustin Moskovitz and Chris Hughes, had the idea of a new social network and elaborated still when they were students at Harvard University, in Massachusetts, in the United States.
The term was taken from albums that the children do, in the United States, placing the photographs of the colleagues of the school or the class, and although the translation may not be a common expression in Brazil, not sounding good in Portuguese, the original idea caught on, coma intention that each person would share their photo and personal information, creating networks and groups where they could share ideas and facts.
In the beginning, the Facebook just accepted the accession of students from the University where its creators studied, and later to other schools and eventually take up the entire established network over the internet.
The Facebook always be guaranteed that it will be free, generating their revenue from advertising, inserting advertising banners and sponsored ads. In the social network, users create their profiles with photos and lists of personal interests, using the same to exchange messages, both public and private (inbox) between the friends and the participants of the groups that are formed.
On Facebook, the viewing of detailed data about the members is restricted to friends or members of the group, who need to confirm their participation, and may also be free and available to all, depending on the will of the creator of the profile.
The Facebook has several tools, among them the wall, a space on the profile page that allows you to post message of friends. Posts (or blog posts) can appear in News Feed, separate and available if the user want to know more about the subjects that are being discussed on the network.
With the time, several applications were being inserted in Facebook, with a range of issues, with the disclosure of the events and with the possibility to invite friends and interested parties. The network already has also with applications that allow you to earn money on the internet, through Facebook Ads, sponsored advertisements for products or events.
