This paper reviews some of the controversy surrounding "Sesame Street's" treatment of the socialization progress of preschool television viewers. Examined in detail are those portions of "Sesame Street" programs which contribute to children's learning of socially acceptable attitudes and behaviors. Some comparisons are made between "Sesame Street" programs aired during the initial 1969-70 season and a sampling of the more recent program segments. Research proposed by the Children's Television Workshop and the Harvard Center for Research should provide additional information concerning "Sesame Street's ability to positively affect the behavior of young children.
