We have been living in a world where social networking exists for quite some time. People have been getting together in communities to discuss topics they have in common for a very long time. Although online social networks like email, message boards, blogs, etc. have been there since the early days of the Internet, they have grown fast in recent years. O'Reilly (2004) coined the term "Web 2.0" to describe the evolution of social media. In his book, "Reinventing the Web," Tim O'Reilly argues that the ease with which individuals may create and distribute their own material online is fundamentally changing the Internet. Web 2.0 made media social by allowing people to easily share and receive information. To process the meanings of its users, the Internet has given rise to a new social phenomenon: social media. However, social media are not a separate set of media or sub-form on top of the networking system. With the advent of mobile devices like PCs, mobile phones, PDAs, and game consoles, plus the widespread availability of broadband and WiFi connections, anybody with an internet connection may freely access any Web 2.0 resource like a wiki, video sharing website, or blog. Blogs, chat rooms, social networking sites, forums, and message boards are just a few examples of the many channels of communication made possible by social media; they may be broken down into three main types: content syndication, content sharing, and community development. Blogs, podcasts, and videocasts are all forms of content syndication; user-generated content, wikis, and widgets are all forms of content sharing; and social networks and online communities are all forms of community development.
