Social life has always been mediated and media has always been social. From stone tablets to touchscreens, expressions of self and connections with others flow through and are shaped by, the media systems of a time. Mass media and social media are the predominant modes of mediation today, integral to daily life in ways both public and personal, momentous and mundane. Established theories from sociological social psychology can reveal how media systems affect and are affected by dynamic social forces. In turn, studies of media can spur theoretical advancement. Sociological social psychology is premised on the active interplay between micro, meso, and macro. Media stream through these multiple levels, implicated in self-presentation and evaluation, interpersonal relations, organizational infrastructures, and the structural patterns of societal institutions. This chapter casts sociology’s social psychological lens onto a mediated society through focal topics of identity, status, and social movements, all of which traverse layers of action and interaction at the intersections of mass media, social media, and society.
