This chapter examines the effect of TV debates on political knowledge conditioned by the media context. We argue that TV debates take place in a wider media context and the extent of citizens’ learning processes about issue positions depends also on the informational context in general. We test four hypotheses: while the first three hypotheses concern the conditional impact of media issue coverage and debate content, the last hypothesis addresses the differences between incumbent and challenger. Using media content analyses and panel survey data, our results confirm the hypotheses that (1) when an issue is addressed in a TV debate, viewers tend to develop a perception of the parties’ positions on this issue, but (2) only if this issue has not been addressed extensively in the media beforehand. This learning effect about parties’ positions is bigger for the opposition party.
