As the internet and new online technologies are becoming embedded in everyday life, there are increasing questions about their social implications and consequences. Children, young people and their families tend to be at the forefront of new media adoption but they also encounter a range of risky or negative experiences for which they may be unprepared, which are subject to continual change. This book captures the diverse, topical and timely expertise generated by the EU Kids Online project, which brings together 70 researchers in 21 countries across Europe. Each chapter has a distinct pan-European focus resulting in a uniquely comparative approach.
