that 20 million copies of The Monster at the End of the Book and Another Monster at the End of this Book had been sold, making them the top two best-selling e-books sold. Its YouTube channel had almost 5 million subscribers. Music According to director Jon Stone, the music of Sesame Street was unlike any other children's program on television. For the first time, the show's songs fulfilled a specific purpose and was related to its curriculum. Cooney observed in her initial report that children had an "affinity for commercial jingles", so many of the show's songs were like television advertisements.

Cooney remarked, "To be frank, I was really surprised, because we thought we were creating the quintessential American show. We thought the Muppets were quintessentially American, and it turns out they're the most international characters ever created".
