In May 2009, worldwide, some 1.1 billion people (age 15 and older) access the Internet, either from their home or office. Out of those 1.1 billion people, (65 % of the world’s Web audience) visited minimum one social networking site during the month, making it two-thirds of the global Internet users who  will access social networking websites.
The term social search began to emerge between 2004 and 2005.Social ranking can be considered to derive from googles page rank algorithm.
