The course provides an introduction to the sociological understanding of how information and communication technologies shape contemporary societies. The course focuses on social, cultural, political and economic implications of the diffusion of digital media in late modernity. The lectures provide an overview of the historical development of digital media and discuss various spheres of social life which have been significantly transformed by the presence of digital media: self-presentation, social relationships, political engagement, hate speech, racism, or economy. A focus is given to the politics of social media as well as to the politics through social media. Lectures are accompanied by seminars run in a smaller group of students to allow everyone to engage in discussion through the reflection of reading. The final two weeks of the semester are dedicated to the intense and guided work on a final essay in thematically established groups.
