Ofcom published an interesting report on "Children and parents: Media use and attitudes report 2015". Ofcom is the Independent regulator and competition authority for the UK communications industries.
"The report examines children's media literacy. It provides detailed evidence on media use, attitudes and understanding among children and young people aged 5-15, as well as detailed information about the media access and use of young children aged 3-4.
It also includes findings relating to parents' views about their children's media use, and the ways that parents seek - or decide not - to monitor or limit use of different types of media.
The report is a reference for industry, stakeholders and consumers. It also provides context to the work Ofcom undertakes in furthering the interests of consumers and citizens in the markets they regulate."
