The volume provides an overview of electronic media and their integration into the daily lives of children and adolescents. The starting point is the now widely articulated thesis that the life worlds of young people are also always media worlds. This leads to central questions: How do children and adolescents navigate this extensive media landscape? How do they choose their offerings? What cognitive prerequisites are necessary to understand media content? What individuals and institutions play a role in the media actions of children and adolescents? What challenges are associated with growing up in a media world? And how can potential risks be addressed?.
