Modern election campaigns rely on media, including the press and radio, especially television, and increasingly on the internet and social networks. This applies to both parties and voters. For voters, the media provide an important basis for information and decision-making. For parties and their candidates, they are an indispensable platform for public representation; they serve as advertising vehicles and means of influence to gain votes. Media are also political actors with their own interests, which can influence the course of the campaign and the election outcome through their reporting and expression of opinions. This volume addresses scientific findings and current insights into election communication from traditional mass media, new media, and the advertising media used by parties. It explains the reasons why the media play a crucial role.
