"highly [racially] integrated cast of children" which "the commission members felt ... Mississippi was not yet ready for." According to Children and Television, Lesser's account of the development and early years of Sesame Street, there was little criticism of the show in the months following its premiere, but it increased at the end of its first season and beginning of the second season. Historian Robert W. Morrow speculated that much of the early criticism, which he called "surprisingly intense," stemmed from cultural and historical reasons in regards to, as he put it, "the place of children in American society and the controversies about television's effects on them." According to Morrow, the "most important" studies finding negative effects of Sesame Street were conducted by educator Herbert A. Sprigle and psychologist Thomas D. Cook during its first two seasons. Social scientist and Head Start founder Urie Bronfenbrenner criticized the show for being too wholesome. Psychologist Leon Eisenberg saw Sesame Streets urban setting as "superficial" and having little to do with the problems confronted by the inner-city child. Head Start director Edward Zigler was probably Sesame Streets most vocal critic in the show's early years. In spite of their commitment to multiculturalism, the CTW experienced conflicts with the leadership of minority groups, especially Latino groups and feminists, who objected to Sesame Streets depiction of Latinos and women. The CTW took steps to address their objections. By 1971, the CTW hired Hispanic actors, production staff, and researchers, and by the mid-1970s, Morrow reported that "the show included Chicano and Puerto Rican cast members, films about Mexican holidays and foods, and cartoons that taught Spanish words." As The New York Times has stated, creating strong female characters "that make kids laugh, but not...as female stereotypes" has been a challenge for the producers of Sesame Street. According to Morrow, change regarding how women and girls were depicted on Sesame Street occurred slowly. As more female Muppet performers like Camille Bonora, Fran Brill, Pam Arciero, Carmen Osbahr, Stephanie D'Abruzzo, Jennifer Barnhart, and Leslie Carrara-Rudolph were hired and trained, stronger female characters like Rosita and Abby Cadabby were created. In 2002, Sesame Street was ranked number 27 on TV Guide's 50 Greatest TV Shows of All Time. Sesame Workshop won a Peabody Award in 2009 for its website, sesamestreet.org, and the show was given Peabody's Institutional Award in 2019 for 50 years of educating and entertaining children globally.
