This book offers a wide-scale, interdisciplinary analysis and guide to social media and political communication, examining the political use of social media platforms such as Twitter, Facebook, Instagram and TikTok. From disinformation to artificial intelligence, Jeremy Lipschultz explores how social media tools are being deployed by "good" and "bad" political actors. The use of "fake news" or disinformation is clearly contextualized for readers within a wider understanding of the historic uses of propaganda, persuasion and political advertising. Lipschultz also examines how social media is used by activists and social movements to increase civic engagement and amplify social issues. The book surveys traditional media communication theories and methods, exploring newsgatekeeping, propaganda, persuasion and personal influence, and diffusion of new technologies and ideas, teaching vital critical thinking methods for consuming, engaging with, and understanding political social media content from a media literacy perspective. It also includes social network analyses which offer visual representations of social media crowds that influence social movements and political change. Essential reading for students of Media and Cultural Studies, Communication, Journalism, Political Science, and Information Technology, as well as anyone wishing to understand the current intersection of social media and politics.
