Communication technologies, such as computers and cell phones, and social-networking sites like My Space enable the rapid creation and dissemination of harassing and pornographic text, pictures, and video. Studies show that whereas adults generally use technology only as a tool, adolescents consider technology, including text messaging and chat rooms, to be an essential part of their social life. Cyberbullying and victimisation begin as early as second grade for some children, and by middle school, students as a group experience or engage in all known forms of cyber abuse and on-line aggression. Online exchange of sexually explicit content typically begins in middle school. This book provides an annotated bibliography, provisions of select federal and state laws, and major cases of internet crimes against children.
