Capt Crouton-- Sesame Street was not dumbed down for younger viewers because it is not a strong show. The people behind Sesame Street-- a team comprised of television professionals, child psychologists, sociologists, educators and other experts-- regularly rework the show, or parts of the show to make it the best show they can.
The Sesame Street core audience, that is the majority of the people watching, have been getting younger for years. What works well for a six year old may not work for a three year old. Sesame Street responds to the needs of its audience by tweaking the show and keeping it age appropriate. While, as an adult Muppet fan, I have been slow to accept some of the changes, as a parent I whole heartedly support them.
The ever increasing number of children's shows has increased competition for Sesame Street. The declining social constraints on television for young kids means younger children are watching. People used to believe two year olds were too young for TV and would not enjoy it nor understand it. We can still debate whether a two year old-- or a one year old-- should watch television but most of us have come to realise a child that young does enjoy it and is able to comprehend some of it.
So, as I see it, Sesame is responding to consumer demand. It it the show's ability to change and stay current that keeps it as the model of children's programming.
It is an odd time in this country when Jerry Falwell supports a 'liberal' idea and some of the Republicans in congress do not. Especially when it is something happening on the other side of the world.
Too bad we can't have these lawmakers work on getting American drug companies to offer more HIV and AIDS medications to African nations at reduced prices.... Now that would truly be helpful.
