Based on evidence from the 18 countries included in the 2021 Media for Democracy Monitor (MDM), this chapter provides the first comparative analysis of whether and how the issue of online misinformation is being interpreted and dealt with in newsrooms around the world. We analyse to which degree news media view online misinformation as a challenge that needs addressing and what measures they take to avoid relaying online misinformation. Moreover, we study how news media form part of broader societal and regulatory initiatives to counter misinformation. The chapter identifies different national approaches to the news media’s ways of addressing online misinformation, and we discuss potential future avenues for research and regulatory action.
