Sésamo (English: Sesame), formerly titled Plaza Sésamo (English: Sesame Plaza) prior to 2016, is one of the first international co-productions of the American children's television program Sesame Street. Its first season premiered in Mexico in 1972, and the last season ended in 2018 during the holiday season and the 50th anniversary of Sesame Street, but the show returned in 2020 and was immediately a ratings hit. It also aired throughout Latin America, to a potential audience of 25 million children in 34 countries. Unlike some of the earliest co-productions, which consisted of dubbed versions of Sesame Street with local language voice-overs, Sésamo was a true co-production. Half of the show was adapted from the American show, and half was original material, created in Mexico by Mexican writers, performers, and producers. The first season consisted of 130 half-hour episodes. The Plaza Sèsamo development process was similar to that of the American show. Its goals were developed by local experts in television, child development, and early education during curriculum seminars in Caracas, Venezuela. Sésamo's goals emphasized problem solving and reasoning, and also included perception, symbolic representation, human diversity, and the child's environment. Other goals included community cooperation, family life, nutrition, health, safety, self-esteem, and expressing emotions. Early reading skills were taught through the whole language method. The show's budget for the first and second seasons was approximately US$1.6 million.
