Children in the United States are exposed to many influences other than that of their families．Television is the most significant of these influences，because the habit of watching television usually begins before children start attending school．

Parents are concerned about the lack of quality in television programs for children．The degree of violence in many of these shows also worries them．Studies indicate that，when children are exposed to violence，they many become aggressive or insecure.

Parents are also concerned at，out the commercials that their children see on television． Many parents would like to see fewer commercials during programs for children．And some parents feel that these shows should not have any commercials at all because young minds are not mature enough to deal with the claims made by advertisers．

Even though most parents and educators give Sesame Street and shows like it high marks for quality，some critics argue that all television，whether educational or not，is harmful to children．These critics feel that the habit of watching hours of television every day turns children into bored and passive(被动的)consumers of their world rather than encouraging them to become active explorers of it．
