Political Communication in the Age of Platforms

Political communication has been extensively studied through both the broader context of societal and political systems, as well as through the lens of mediatization, which emphasizes the intersection of political and media logics. Within this framework, scholars originally identified three distinct stages or eras of political communication. However, recent scholarship has increasingly focused on the transition to a “fourth” era, characterized by the growing impact of digital and social media. This shift, from the “television age” to the “social media age”, has not only introduced new media channels for conveying political messages but has also fundamentally transformed the nature of political communication itself—shifting from top-down, centralized models to more horizontal, decentralized forms of interaction. Current research on the role of social media in political communication reveals a complex landscape. These platforms appear to both enhance and undermine established processes of political deliberation. On the one hand, they provide new avenues for civic engagement and political discourse, while on the other, they contribute to issues such as disinformation, polarization, and the erosion of privacy. This entry aims to offer a comprehensive review of how social media platforms have reshaped the dynamics of political communication and civic participation. It further explores the challenges that accompany these transformations, such as the spread of disinformation, rising political polarization, increasing incivility, and privacy concerns stemming from advanced digital marketing techniques in political contexts.
