Sesame Street was originally designed as a way to give kids who couldn't go to preschool the same kind of counting and reading lessons so that they wouldn't fall behind in kindergarten. The original target was poor inner city kids, but now it reaches all over the world teaching kids their abcs and tolerance and kindness.
Just to show how very affecting this little experiment was, I don't know a single person my age who wouldn't finish the line if I started singing "1,2,3,4,5"
And I still joke when I'm making a grocery list "a loaf of bread, a container of milk, and a stick of butter"
May Sesame Street have another 40 years of of being one of the best damn things America has ever exported.
