Read the passage. Transforming Children's Television Mister Rogers' Neighborhood, created by Fred Rogers, first appeared on national television in 1968. Rogers developed the program in order to address what he perceived as a deficiency in television programming for young children; specifically, he viewed traditional programming as neglectful of social and emotional issues. One year after the show's national debut, another new public television children's program was introduced: Sesame Street, the brainchild of Joan Ganz Cooney and Lloyd Morrisett. Like Rogers, Coone and Morrisett were dissatisfied with the options available for young children. They created Sesame Street in order to add an educational option to children's programming. While Sesame Street was more academically focused than Mister Rogers' Neighborhood, both programs were unusual in their tackling of complicated issues, such as divorce, disability, and the human impact of natural disasters, which were typically ignored by traditional children's television shows.
