The worlds greatest show (almost)!
Sesame Street a a show on PBS made by CTW (Now known as Sesame Workshop) where they teach you to count and the alphabet (which is used in acronyms like PBS and CTW) and is quite entertaining too.
It's designed to be watched by children and adults together because studies show that kids learn more if they watch with their parents. Unfortunately, most parents view the TV as a babysitter.
Of course, Sesame Street isn't just a TV show anymore. There have been at least two Sesame Street Movies (Follow That Bird and The Adventures of Elmo in Grouchland), many toys (Tickle Me Elmo was the number one selling toy in 1996), books (Sesame Street Unpaved is awesome!), and albums (Rubber Duckie was a smash hit in Germany).
Sesame Street has aired in over 140 countries world-wide, both the American version or a local version.
