With the ascendance of liberal democracy, propaganda activities have vastly increased. The main aim of propaganda has been to protect state-corporate power from the threat of public understanding and participation. Because of its societal importance for public opinion formation, the news media constitutes an obvious channel for the dissemination of propaganda. However, contemporary communication, media and journalism studies have mostly neglected to critically assess the news media's role in producing and distributing propaganda. In fact, despite of the news media's integration into the state-corporate nexus, the term propaganda is rarely used in academic treatises on the news media. Furthermore, only a small number of scholars have engaged in elaborating a systematic understanding of the manifold propaganda techniques that are currently applied in liberal democracies. To fill these research gaps, this article maps out various concepts of propaganda and relates them to the process and content of the news media. On the basis of theoretical and empirical studies, the article demonstrates how different forms of propaganda can manifest in news media content. Based on an integration with, as well as a development of, existing literature, the essay aims to build a tool box that can be applied and refined in future studies in order to detect propaganda in news media texts.
