This study focuses on the formation of far-right online communities on YouTube and whether the rise of three new actors (Pegida, Identitarian movement, AfD) can also be observed with user behavior on YouTube. We map the network of far-right, conspiracy and alternative media channels in the German-language YouTube sphere, how this network evolves over time and identify the topics that users discuss. Our analysis shows that the overall common denominator within the German far-right YouTube sphere is the refugee crisis and the problems associated with it. Furthermore, we show that the community is getting denser and more centralized over time.
