Big changes in store for Sesame Street, including more focused narratives and features aimed at a younger audience (2-year-olds instead of three-to-fives). If the sort of child development theory discussed in the article is interesting to you, I highly suggest you check out The Tipping Point by Malcolm Gladwell, which has a chapter on how children’s TV producers design their programs to match what we know about how children learn. (Very brief excerpt here. The book’s actually mostly about other stuff, and well worth reading even if you hate children and never were one.)
