By 2002, "Blue's Clues" had received several awards for excellence in children's programming, educational software, and licensing, and had been nominated for nine Emmy Awards. It has been syndicated in 120 countries and translated into 15 languages. Regional versions of the show featuring local hosts have been produced in other countries. It was one of the first preschool shows to incorporate American Sign Language into its content. The show's extensive use of research in its development and production process inspired several research studies that have provided evidence for its effectiveness as a learning tool.
