Social networking has been an integral part of our life, before the advent of internet era people used to communicate personally or through mobiles or phones but people today are connecting themselves through Social Networking Sites. Social Network Sites (SNSs) such as MySpace, Facebook, Cyworld, and Bebo have attracted millions of users. It’s nearly impossible in this day and age not to know about Facebook. Facebook is a social networking site that started out strictly for college students and was available by invitation only. According to the Pew Internet Project, Facebook is the most dominant social network among teens, used by 85% of teenagers who use social networks. Facebook was designed to support distinct college networks only. Facebook began in early 2004 as a Harvard-only SNS. To join, a user had to have a harvard.edu email address. Beginning in September 2005, Facebook expanded to include high school students, professionals inside corporate networks, and, eventually, everyone. With over 30 million unique users, Facebook in India is growing at an average of 7-8% every month.
