Facebook is the world’s largest social network, with over 1 billion monthly active users. Facebook announced astonishing numbers in February 2012 upon filing for its IPO. Over 845 million users log into Facebook every month, and 483 million users log in daily. Mobile users now make up half of Facebook’s user base, with 425 million monthly actives. Facebook also announced that by the end of 2011 there had been 100 billion friend connections, and in recent months users had been registering 2.7 billion Likes and Comments per day. Facebook is one of the most trafficked sites in the US, and its international growth has been impressive. Additionally, Facebook is the top photo sharing site with 250 million photos uploaded per day. Facebook users’ passion—or addiction—to the site is unparalleled: more than half use the product every single day and users spend an average of 19 minutes a day on Facebook.
