Facebook inc.

Facebook is a web application that connects people; Facebook's mission is to give people the power to share and make the world more open and connected. Millions of people use Facebook everyday to keep up with friends, upload an unlimited number of photos, share links and videos, and learn more about the people they meet.

Facebook has been established by M. Zuckerberg, a Harvard student, on 4 February 2004 in the USA, and listed on the NASDAQ in May 2012. The listing price is being analysed by US authorities because of the excess volatility registered in the very few days on the NASDAQ.
