Social media are computer-mediated tools that allow people to create, share or exchange information, ideas, and pictures/videos in virtual communities and networks. Andreas Kaplan and Michael Haenlein define social media 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." Furthermore, social media depend on mobile and web-based technologies to create highly interactive platforms through which individuals and communities share, co-create, discuss, and modify user-generated content. They introduce substantial and pervasive changes to communication between organizations, communities, and individuals. These changes are the focus of the emerging field of technoself studies. Social media are different from traditional or industrial media in many ways, including quality, reach, frequency, usability, immediacy, and permanence. There are many effects that stem from internet usage. According to Nielsen, internet users continue to spend more time with social media sites than any other type of site.
