The following text discusses media studies.

The concept of "agenda-setting" describes how media influence not what people think but what they think about. By covering certain issues extensively while ignoring others, media shape public perception of what matters. During election campaigns, issues receiving heavy coverage become voters' priorities—not because voters are told what to believe but because coverage signals importance. Digital media has complicated this theory: with more sources and user curation, who sets the agenda becomes contested. Yet studies show social media may concentrate attention even more intensely on fewer trending topics.
