This book is an illuminating study of the complex relationship between children and media in the digital age. Now, as never before, young people are surrounded by media, thanks to the sophistication and portability of the technology that puts it literally in the palms of their hands. Drawing on data and empirical research that cross many fields and continents, this book examines the role of media in the lives of children from birth through adolescence, addressing the complex issues of how media affect the young and what adults can do to encourage responsible use in an age of selfies, Twitter, Facebook, and Instagram. The book looks at both the sunny and the dark side of media use by today's youth, including why and how their preferences change throughout childhood, whether digital gaming is harmful or helpful, the effects of placing tablets and smartphones in the hands of toddlers, the susceptibility of young people to online advertising, the legitimacy of parental concerns about media multitasking, and more.
