What effect does media exposure have on our children? This question has sparked heated debates over the past few years. With the introduction of each new media format or technology, a fresh debate develops concerning the potential negative effects it might have on kids. Educators, parents, social scientists, media analysts and many others all offer their opinions but rarely are compromises reached. Some state that in order to protect children, government regulation is needed; others argue the fact that parents have many constructive alternatives. "There has never been a time in our nation's history when parents have had more tools and methods at their disposal to help them decide what is acceptable in their homes and in the lives of their children," concludes Adam Thierer, in his new book, "Parental Controls & Online Child Protection: A Survey of Tools and Methods."
