In the context of American government and politics, the term refers to individuals or groups that control access to information and decision-making processes. These entities, which can include media outlets, political parties, interest groups, and even influential individuals within government, determine which issues gain public attention and which perspectives are heard. For example, a major news network choosing to cover a specific political scandal over another is acting in this capacity, shaping public discourse.
The significance of these actors lies in their power to influence public opinion, set the political agenda, and ultimately impact policy outcomes. Understanding their role is crucial for analyzing the dynamics of political communication and the formation of public policy. Historically, these roles have evolved alongside technological advancements in communication, from print media to broadcast television and now, the digital landscape.
