Children and young people go online virtually every day. International data on children and online media is extensive, heterogeneous and partly contradictory. Our aim is to create a comprehensive pan-European knowledge platform with the participation of international researchers, educators, policy makers and concerned dialogue groups. Providing an overview of the research situation, enabling access to empirical data, distributing policy recommendations and offering resources for education lie at the heart of our work. cover photo: https://bit.ly/unsplash-croset
