This book explores the changes in political communication in light of the development of a public opinion mediated by web 2.0 technologies. One of the most important changes in political communication is related to the process of disintermediation, i.e. the process by which digital technologies allow citizens to compete in the public space with those agents who, traditionally, co-opted public opinion. However, while disintermediation has undeniably generated a number of advances, having linked citizens to the public debate, the authors highlight some aspects where disintermediation is moving away from a rational and inclusive public space. They argue that these aspects, related to the immediacy, polarization and incivility of the communication, obscure the possibilities for democratization of digital political communication.

This book discusses the implications of recent innovations in information and communication technology for civic and political engagement. The international mix of contributions offers insights across a broad spectrum of studies into the form of engagement: explaining the reasons, incentives and motivations for engaging, and the different forms and levels of engagement; contrasting traditional and non-traditional forms of engagement and how they interlink; and asking why people utilize or avoid certain forms of engagement. It is a must-read for any scholar interested in the impact of social media on citizens’ propensity to get involved in political actions. It depicts the role that parties, organizations and peers play in mobilizing or demobilizing others and how online behaviour can act as a springboard into what might be called real-world politics. The book gathers together prominent scholars, who offer their understanding of social and political phenomena and give theoretical and empirical insights into the highly complex questions around political participation in the digital age. ​ This book was originally published as a special issue of Political Communication.

This element shows, based on a review of the literature, how digital technology has affected liberal democracies with a focus on three key aspects of democratic politics: political communication, political participation, and policy-making. The impact of digital technology permeates the entire political process, affecting the flow of information among citizen and political actors, the connection between the mass public and political elites, and the development of policy responses to societal problems. This element discusses how digital technology has shaped these different domains, identifies areas of research consensus as well as unresolved questions, and argues that a key perspective involves issue definition, that is, how the nature of the problems raised by digital technology is subject to political contestation.

Much time has been spent over the past decade debating whether social media contribute to democracy. Drawing on an original study of internet users across nine Western democracies, Outside the Bubble offers an unprecedented look at the effects of social media on democratic participation. This book argues that social media do indeed increase political participation in both online and face-to-face activities--and that they expand political equality across Western democracies. In fact, Cristian Vaccari and Augusto Valeriani find that, for the most part, social media do not constitute echo chambers or filter bubbles as most users see a mixture of political content they agree and disagree with. Various political experiences on social media have positive implications for participation and active political involvement: social media allow citizens to encounter clearly identifiable political viewpoints, facilitate accidental exposure to political news, and enable political actors and ordinary citizens to reach voters with electoral messages designed to mobilize them. Moreover, political interactions occurring on social media do not only benefit citizens who are already involved, but boost participation across the board. This is because social media offer both additional participatory incentives to the already engaged and new political opportunities for the less engaged. By adopting a comparative approach, Vaccari and Valeriani also show that political institutions matter since some political experiences on social media are more strongly associated with participation in majoritarian systems and in party-centric systems. While social media may contribute to many societal problems, they can help address at least two important democratic ills: citizens' apathy towards politics, and inequalities between those who choose to exercise their voice and those who remain silent.

Donald Trump, the Arab Spring, Brexit: digital media have provided political actors and citizens with new tools to engage in politics. These tools are now routinely used by activists, candidates, non-governmental organizations, and parties to inform, mobilize, and persuade people. But what are the effects of this retooling of politics? Do digital media empower the powerless or are they breaking democracy? Have these new tools and practices fundamentally changed politics or is their impact just a matter of degree? This clear-eyed guide steps back from hyperbolic hopes and fears to offer a balanced account of what aspects of politics are being shaped by digital media and what remains unchanged. The authors discuss data-driven politics, the flow and reach of political information, the effects of communication interventions through digital tools, their use by citizens in coordinating political action, and what their impact is on political organizations and on democracy at large.

Big data raise major research possibilities for political communication scholars who are interested in how citizens, elites, and journalists interact. With the availability of social media data, academics can observe, on a large scale, how people talk about politics. The opportunity to study political discussions is also available to media organizations and political elites—examining how they make use of big data represents another fruitful scholarly trajectory. The scholars involved in Digital Discussions represent forward thinkers who aim to inform the study of political communication by analyzing the behavior of and messages left by citizens, elites, and journalists in digital spaces. By using a variety of methodological approaches and bringing together diverse theoretical perspectives, this group sheds light on how big data can inform political communication research. It is critical reading for those studying and working in communication studies with a focus on big data.

This book explores how digital media use affects political attitudes and behavior, and how this relationship is shaped by political environments across countries. While research in this area has concentrated on the United States and United Kingdom, such results are set in comparative relief through the analysis of cases across Europe, Latin America, the Middle East, and Asia. The book concludes that digital media have an effect on users, and depicts some of the characteristics of different political systems that play a significant role for online political engagement.
