There are a variety of tools to help parents manage what their children see on TV, including: the TV rating system, on-air advisories and warnings, the v-chip in your television and parental controls on cable and satellite.
TV ratings provide information about the content and age-appropriateness of programs and can be found with most program listings (see tvguidelines.org to learn more about the ratings).
Don't assume that if a program is nonviolent or on PBS it will necessarily be consistent with your values. Try to watch at least one episode of a new program that your child wants to watch to make sure that you approve of the show’s content for your child.
