Social media are computer-mediated tools that allow people to create,
share or exchange information, ideas, and pictures/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."[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 techno
self-studies. Social media are different 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 monologist transmission model (one source to many receivers).
