Representations in media do not present reality directly, but re-present events and ideas in certain ways that invite audiences to understand and agree with preferred interpretations. Whatever representations are used implicitly contain ideologies and values that give media institutions power to influence social attitudes towards groups. Stereotypes are an extreme form of representation that focus on and exaggerate certain aspects to allow audiences to instantly identify meanings, but they are usually negative oversimplifications that make assumptions, especially about minority or disadvantaged groups.
