This book explores the pervasive and globalized trajectory of domestic disinformation. It describes specific operations and general apparatuses of disinformation that are sponsored by the State institutions in several countries around the world, such as governments, political parties, and politicians. With an international team of expert authors, this volume meticulously scrutinizes instances of State-sponsored disinformation across a diverse spectrum of 14 countries encompassing Western and Eastern Europe, North and Latin America, Africa, Asia, and the Middle East. It examines how political landscapes amplify or constrain disinformation, advancing a comprehensive understanding of its dynamics in the contemporary global milieu. The book is organized in three sections that gather case studies from democratic, non-democratic and transitional regimes. Advancing the field of misinformation and disinformation studies by specializing in State-sponsored operations and their consequences, this book will be an essential volume for scholars and upper-level students of media and communication studies, journalism, political communication, disinformation and misinformation, social media, sociology and international politics.
