How does the media influence the policy agenda of the President and the public agenda of the American public?

Today, many political analysts agree in classifying journalism and the media as the fourth branch of democracy, in addition to the Executive Branch, the Legislative Branch and the Judicial Branch. This means, according to these analysts, that journalism exercises a determining power within the framework of democracy, decisively influencing public opinion in society and establishing issues of interest to citizens.

Ultimately, there is a covert manipulation through the dissemination of news, which implies that citizens consume a certain agenda or ideology through them. Thus, the media modify the public agenda, creating needs in the citizenry, which begins to demand these from the politicians, modifying in turn the political agenda of the nation.
