INTRODUCTION TO COMMUNICATION MEDIAAgenda-Setting Theory

Agenda-Setting Theory

may not be successful much of the time in telling people what to think, but it is stunningly successful in telling its readers what to think about

Cultivation Theory

is concerned with how prolonged, cumulative exposure to television gradually shapes viewers' broader perception of social reality — how dangerous, generous, or trustworthy the world seems to be.

Framing theory

closely related to the second level of agenda-setting; examines how the presentation of an issue (word choice, imagery, emphasis) shapes audience interpretation

Gatekeeping theory

examines how editors, producers, and now algorithms decide which stories pass through the “gates” to reach the public at all.

Uses and gratifications theory

shifts the focus from what media does to people, to what people actively seek from media (information, entertainment, social interaction

The Role of Mass Media in Shaping Public Opinion

Gatekeeping

deciding which events become “news” in the first place, out of the far larger number of events that occur each day

Agenda-setting

determining which of those selected stories receive the most prominent, repeated coverage, thereby signaling to the public which issues matter most.

Repetition and cultivation

reinforcing particular worldviews over time through the cumulative pattern of coverage, not just a single story.

The Evolution of Journalism

The Partisan Press

The earliest American newspapers were largely funded by and loyal to political parties, publishing openly one-sided political commentary rather than neutral reporting.

The Penny Press

used cheaper production technology (including the linotype machine) and street-corner newsboys to reach a genuinely mass, working-class readership for the first time, shifting newspaper content away from partisan commentary and toward crime, human interest, and local news

Yellow Journalism

exaggerated or fabricated stories, and a clear prioritization of sales over accuracy (EBSCO, n.d.-c; Fiveable, n.d.-a). This era is widely credited with prompting the earliest serious debates about journalistic ethics and responsibility

Broadcast and Investigative Journalism

As radio and television matured (see Unit 2), journalism expanded into broadcast newsrooms, and investigative and interpretive journalism grew in prominence — exemplified by the Watergate reporting of Bob Woodward and Carl Bernstein in the 1970s, which remains a textbook example of journalism's watchdog function (Vocal Media, 2024).

Digital and Social Journalism

The internet and social media (Unit 2, Section C) have most recently reshaped journalism again: news now travels instantly, audiences can publish their own eyewitness reporting, and traditional outlets compete directly with social platforms for attention — developments that connect directly to the media-ownership and regulation questions discussed in Unit 6.

Seek truth and report it

verify information before publishing, provide a fair and comprehensive account, and clearly distinguish factual reporting from opinion or commentary.

Minimize harm

balance the public's need for information against the potential harm or distress that coverage may cause, showing particular sensitivity toward minors, victims of crime, and vulnerable sources.

Act independently

avoid conflicts of interest, and remain free of outside political, financial, or personal influence that could compromise impartiality

Be accountable and transparent

explain editorial decisions to the public, and promptly and visibly correct factual errors.

FCC's media ownership rules

Viewpoint diversity

media content reflecting a range of perspectives

Programming diversity

a variety of formats and content, including programming aimed at different minority and ethnic groups

Outlet diversity

the presence of multiple, independently owned outlets within the same geographic market.

Minority and female ownership

broadening who owns and controls broadcast outlets, not just what they broadcast.

Media Monopolies and Their Effects on Diversity and Content

Homogenization of content

outlets owned by the same parent company increasingly share or “recycle” centrally produced content rather than each producing original reporting, so audiences across different markets end up consuming more of the same material

Decline in local news

when local outlets are acquired by conglomerates, local reporting tends to decrease as companies rely more on syndicated or shared content, sometimes producing “news deserts” — communities with little or no dedicated local coverage (Oxford Academic Journal of Communication, 2025; ProMarket, 2025)

Narrower range of viewpoints

when a small number of firms control most outlets, the range of editorial perspectives that reach the public can shrink, potentially underrepresenting minority or dissenting viewpoints (Fiveable, n.d.-d).

Reduced accountability journalism

as some researchers note, cost-cutting under consolidated ownership can come at the expense of investigative and in-depth reporting, which is more resource-intensive than syndicated content
