<P> During the production of Sesame Street's first season, producers created five one - hour episodes to test the show's appeal to children and examine their comprehension of the material . Not intended for broadcast, they were presented to preschoolers in 60 homes throughout Philadelphia and in day care centers in New York City in July 1969 . The results were "generally very positive"; children learned from the shows, their appeal was high, and children's attention was sustained over the full hour . However, the researchers found that although children's attention was high during the Muppet segments, their interest wavered during the "Street" segments, when no Muppets were on screen . This was because the producers had followed the advice of child psychologists who were concerned that children would be confused if human actors and Muppets were shown together . As a result of this decision, the appeal of the test episodes was lower than the target . </P> <P> The Street scenes were "the glue" that "pulled the show together", so producers knew they needed to make significant changes . The producers decided to reject the advisers' advice and reshot the Street segments; Henson and his coworkers created Muppets that could interact with the human actors, specifically Oscar the Grouch and Big Bird, who became two of the show's most enduring characters . These test episodes were directly responsible for what writer Malcolm Gladwell called "the essence of Sesame Street--the artful blend of fluffy monsters and earnest adults". Since 2001, the full rights for the Muppets created for Sesame Street have been owned by Sesame Workshop . </P> <Table> <Tr> <Th> Character </Th> <Th> Actor / Muppet performer </Th> <Th> Description </Th> </Tr> <Tr> <Th> Abby Cadabby </Th> <Td> Leslie Carrara - Rudolph </Td> <Td> A 4 - year - old fairy - in - training with tiny wings, a magic wand, and sparkles in her hair .
