From 'Covfefe' to #FraudNewsCNN and #FakeNews, Donald Trump's tweets have caused an international frenzy. He is a reality TV and Twitter-President, who uses digital and entertainment culture as an ideological weapon - as an expression of his authoritarianism. This book delves into new political-economic structures as expressed through political communication to explain the rise of authoritarian capitalism, nationalism and right-wing ideology throughout the world. Christian Fuchs does this through updating Marxist theory and the Frankfurt School's critical theory. He re-invigorates the works on authoritarianism of Franz L. Neumann, Theodor W. Adorno, Erich Fromm, Herbert Marcuse, Max Horkheimer, Wilhelm Reich, Leo Löwenthal and Klaus Theweleit in the age of Trump and Twitter. In the age of big data and social media, Digital Demagogue studies the expressions of ideology, nationalism and authoritarianism today and discusses prospects for overcoming capitalism and renewing the Left.

Christian Fuchs is a leading critical theorist of communication and society. He is a Professor at the University of Westminster, co-editor of the open access journal tripleC: Communication, Capitalism and Critique, and the author of Digital Demagogue (Pluto, 2018) and Social Media: A Critical Introduction (Sage, 2017) amongst other works.
