Blue's Clues became the highest-rated show on American commercial television and was critical to Nickelodeon's growth. It has been called "one of the most successful, critically acclaimed, and ground-breaking television series of all time". A spin-off called Blue's Room premiered in 2004. Blue's Clues & You!
The show's producers and creators presented material in a narrative format instead of the more traditional magazine format, used repetition to reinforce its curriculum, and structured every episode the same way. They used research about child development and young children's viewing habits that had been conducted in the thirty years since the debut of Sesame Street in the U.S., and revolutionized the genre by inviting their viewers' involvement. Research was part of the creative and decision-making process in the production of the show, and was integrated into all aspects and stages of the creative process. Blue's Clues was the first cutout animation series, and resembled a storybook in its use of primary colors and its simple construction paper shapes of familiar objects with varied colors and textures. Its home-based setting was familiar to American children, but had a look unlike other children's TV shows. A live production of Blue's Clues, which used many of the production innovations developed by the show's creators, toured the U.S. starting in 1999. As of 2002, over 2 million people had attended over 1,000 performance
