This sixth volume in Christian Fuchs' Media, Communication and Society series draws on radical Humanist theory to address questions around the digital public sphere and the challenges and opportunities for digital democracy today. The book discusses topics such as digital democracy, the digital public sphere, digital alienation, sustainability in digital democracy, journalism and democracy, public service media, the public service Internet, and democratic communications. Fuchs argues for the creation of a public service Internet run by public serviceMedia that consists of platforms such as a public service YouTube and Club 2.0, a renewed digital democracy and digital public sphere version of the legendary debate programme formats Club 2 and After Dark. Overall, the book presents foundations and analyses of digital democracy that are interesting for both students and researchers in media studies, cultural studies, communication studies, political science, sociology, Internet research, information science, as well as related disciplines.
