Literature Review
This literature review will explore three theoretical frameworks: first, this literature
review discusses research highlighting diversity in the mass media. Then, it will further examine
how social media has facilitated conversations and action around diversity. Third, the review
will highlight the agenda setting theory, as well as agenda-building theory and framing, and its
presence in the news and public relations.
Diversity in Mass Media
Diversity has a variety of definitions, but in broad terms, it refers to any perceived
differences among people, such as age, race, functional specialty, profession, sexual preference,
geographic origin, lifestyle, or profession (Dobbs, 1996). When it comes to on-screen diversity,
representation matters both on a micro and macro level. For example, when viewers who lack
exposure to diverse populations of people, what happens onscreen is often one way for viewers
to “glean information about the world” (Boboltz & Yam, 2017, para. 22). When this real-world
exposure is lacking, those mass mediated representations can often build, reinforce, or reject
personally held stereotypes, which are categorical assumptions about people based on their race,
gender, age, and/or other identities (Fiske & Neuberg, 1990; Plant & Devine, 1998).
Researchers have found that depictions of African-Americans as criminal and aggressive
in the media help reinforce anti-black prejudices in audiences (Oliver, 1999; Dixon & Lindz,
2000). Audiences, especially those with limited exposure, typically equated these
narrow-minded and negative media representations with the real world, which can lead to racial
minorities experiencing “less attention from doctors to harsher sentencing by judges, lower
likelihood of being hired for a job or admitted to school…” (Bell & Janis, 2011, p. 15).
