The platformization of the public sphere and its challenge to democracy

Democracy depends on a vivid public sphere, where ideas disseminate into the public and can be discussed – and challenged - by everyone. Journalism has contributed significantly to this social mediation by reducing complexity, providing information on salient topics and (planned) political solutions. The digital transformation of the public sphere leads to new forms of media provision, distribution, and use. Journalism has struggled to adapt to the new conditions. Journalistic news values, relevant to democracy, are being replaced by ones relevant to social media platforms’ attention seeking business model. We plead for a broad public debate about the ongoing platformization and about possible policies to ensure a media system that serves and strengthens democracy.
