31. 'Sesame Street'
No kiddie show has ever been as fiercely beloved as this urban utopian fantasy, set in a brownstone neighborhood populated by a multiracial cast of smiling adults, a gigantic yellow bird, a grouch in a garbage can, and math-loving vampires, plus countless talking letters and numbers. It has great songs, but most important, Sesame has soul, which is why the air has stayed sweet for 40 years – or as the Count would say, 45! 46! 47 years!
