‘This is a wide-ranging book which gives valuable insights on emerging contemporary debates on digital democracy, social media and disinformation. The authors have dug deep into the underlying theories while never ignoring everyday empirical evidence. They engage with issues of policy and regulation which are now under scrutiny in democracies around the world. Their analysis is up to date, noting the impact of the digital platforms on disinformation on the COVID-19 pandemic. It is a necessary and timely text.’Professor Leighton Andrews, Cardiff Business School, UK‘The urgency of critical analysis of misinformation and fake news has become even more apparent in the context of COVID-19. Iosifidis and Nicoli offer a very nuanced analysis of this phenomenon from a socio-political perspective, recognising that the circulation of misinformation and conspiracy theories online is not simply a supply-side product of digital affordances, but is grounded in social phenomena such as the rise of populism. They are very much attuned to policy and regulatory issues, as well as technological options, that can address these urgent contemporary challenges.’Professor Terry Flew, Queensland University of Technology, Australia‘This book could not be more timely or relevant to the contemporary struggles with the effects of disinformation on society. The book explores why and how it poses dangers to democratic society and offers and reviews concrete solutions to them.’Professor Robert G. Picard, Reuters Institute, University of Oxford, UK
