Explorations on mediated communication and beyond: Toward a theory of social media

Although robust theories of radio, television, cinema, journalism, and other areas of mass media already exist, the social media sphere has received relatively little original theorizing. Modeled after Berger and Calabrese's (1975) seminal "axioms of human communication" article, this essay takes stock of the existing research on social media, and uses the same approach to theorizing about social media, advancing 7 axioms and 21 theorems, and exploring how the propositions chronicled can be used to build social media theory and improve public relations practice.
