Sesame Street is the most widely watched children’s television series in the world and Sesame Workshop’s longest running show, with 36 years in production. Sesame Street first debuted in 1969 as an hour-long, daily broadcast aimed to help prepare children between two and five years old for grade school. Sesame Street continues to stand out as the most thoroughly developed and researched preschool television program and media offering with a comprehensive curriculum that focuses on the whole child, including cognitive, emotional, physical and social development. Sesame Workshop is a nonprofit organization that creates research-based media to help children reach their highest potential throughout the world. Founded in 1968, Sesame Workshop develops innovative and engaging educational content delivered in a variety of ways, which include television, radio, books, magazines, interactive web and computer software materials, and community outreach. Through a sweeping use of a multimedia platform, Sesame Workshop has been able to successfully develop age-appropriate materials for issues like fear and loss following September 11; childhood obesity, lead poisoning, fire safety, language development, music education, financial literacy and adoption. In addition, Sesame Workshop has developed international coproductions around the world by using its collaborative production and planning model originally applied to Sesame Street to create culturally and socially relevant content. The development of local adaptations of Sesame Street began in the early 1970s, when producers from Brazil, Mexico, Germany, and Canada approached Sesame Workshop independently, and has extended to 25 countries including Russia, Israel, Palestine, Jordan, China, Spain, Portugal, Poland, South Africa, Bangladesh, and Afghanistan.
