Media of digital sovereignty: social graphs and graph names

Graphs are data structures that can be used to depict information about people or objects and their associated properties and connections. One of the most important graphs is what Facebook founder Mark Zuckerberg calls the “social graph”, which depicts individuals, their relationships and interests in the Facebook Cloud. Besides this social graph, the Internet economy is also dominated by a number of other graphs such as the “search graph” (Google), the “consumption graph” (Amazon), and the “interest graph” (Twitter, Pinterest/Tumblr), while actors such as Uber and Lyft are also currently trying to develop mobility graphs. International competition has arisen for the use of such graphs, which is shown by the fact that China, Russia and other countries have developed their own search engines and social networks. Using documents from Leaks (e.g. from Snowden), this project can show that social graphs play a decisive role in the “War on Terror”, and are apparently also regarded as a strategic instrument by nation states. The research project develops both a media-historical and media-theoretical investigation of the origins, changes, and media-technical prerequisites of social graphs.
