Social media software tools that allow people to create, share and exchange information, ideas and photos / videos in virtual communities and networks. Social media is defined as "a group of Internet-based applications that build on the ideological and technological foundations of Web 2.0, and that allow the creation and exchange of user-generated content."
In addition, social media and mobile technologies depend on the Web to create highly interactive platform through which individuals and communities hand, co-create, discuss and modify the content generated by the user. They introduce important changes and widespread communication between companies, organizations, communities and individuals.
These changes are subject in the emerging field of technoself studies. Social media is different from traditional media or industry in many ways, including the quality, scope, frequency, ease of use, immediacy and permanence. Social media operates in a dialogical transmission system (many sources in many receptors). This is in contrast with the traditional media which operates according to a monologue transmission model (one source to multiple receivers).
There are many effects that result from the use of the Internet. According to Nielsen, Internet users continue to spend more time with social media sites than any other type of site. At the same time, the total time spent on social media in the United States through PC and mobile devices increased 99 percent to 121 billion minutes in July 2012 compared to 66 billion minutes in July 2011. For content contributors The benefits of participation in social media exceeded simply sharing the social construction reputation and providing career opportunities and monetary income, as discussed in Tang Gu and Whinston (2012).
