Paddy Leerssen will present new research on the international political economy of platform regulation. He will discuss state-government relationships in the EU and US, and how these have changed under the new Trump presidency and its new alliances with platform oligarchs like Elon Musk and Mark Zuckerberg. Theresa will present findings from her research on platforms and the media sector. Her work explores the intricate and intertwined relationship between platforms and the media, and how these drive concentration and shifting power over (public) opinion formation processes – often to non-European, non-journalistic actors. A key focus of the discussion will be the potentially dangerous consequences of opinion steering and manipulation through social media platforms, as well as the growing dependence of (European) media on technologies provided by Big Tech companies.
