Growth of Social Network Sites

Through social networking, people can use networks of online friends and group memberships to keep in touch with current friends, reconnect with old friends or create real–life friendships through similar interests or groups. Besides establishing important social relationships, social networking members can share their interests with other like–minded members by joining groups and forums. Some networking can also help members find a job or establish business contacts.

Most social networking websites also offer additional features. In addition to blogs and forums, members can express themselves by designing their profile page to reflect their personality. The most popular extra features include music and video sections. Members can read bios of their favorite music artists from the artist's profile page as well as listen to their favorite songs and watch music videos. The video section can include everything from member–generated videos from hundreds of subjects to TV clips and movie trailers.
