Social media are computer-mediated tools that allow people to create, share or exchange information, ideas, and pictures/videos invirtual 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."[1] 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 businesses, organizations, communities, and individuals.[2] These changes are the focus of the emerging field of technoself studies. Social media differ from traditional or industrial media in many ways, including quality,[3] Reach, frequency, usability, immediacy and permanence. Social media operates in a dialogic transmission system, (many sources to many receivers).[4] This is in contrast to traditional media that operates under a monologic transmission model (one source to many receivers).
"Social media has been broadly defined to refer to 'the many relatively inexpensive and widely accessible electronic tools that enable anyone to publish and access information, collaborate on a common effort, or build relationships'"
