The aim of the Net Children Go Mobile project is to provide robust findings of patterns of online use, access, risk and opportunity in relation to children’s mobile access to the internet and to examine the implications for risks, online safety and – for the purposes of this report – the important policy issues which arise. The use of mobile connected devices by children and young people in Europe has undergone remarkable development in recent years with 45% of 9-16 year olds, and 65% of 15-16 year olds now using tablets or smartphones to access the internet on a daily basis (Mascheroni & Ólafsson, 2014). Internet safety guidance, therefore, has to take account not just this dramatic change since the EU Kids Online survey in 2011 (S. Livingstone, Haddon, Görzig, & Ólafsson, 2011) but that, for many young people, mobile technologies are the way they now experience the internet.
