This paper draws on an empirical study about mediatized political communication and its potential effects on citizens. It starts out with an overview of the complex relationship between media and politics by introducing the key concept of mediatization. The public value concept is used as another theoretical framework for the study, which focuses on public-service broadcasting in Germany in particular by evaluating four political talk shows according to their values for a democratic society. Since public-service broadcasting is required to fulfill certain public standards, its value generating function for a democratic society is examined in more detail in a quantitative program analysis. A total of 74 transmissions of four talk shows was chosen and analyzed with regard to their public value as an indicator of quality. Quality, in this context, was operationalized through two of its factors: variety and relevance. The conclusion primarily draws on an analysis of themes and guests to show how public values are generated in the format of political talk shows and how they fulfill their normative functions for a democratic society.
