Can the "most watched" TV show in the world create social change?

Tuesday night I watched PBS's Independent Lens--
They had a documentary aired called
"The World According to Sesame Street"
http://www.pbs.org/independentlens/worldaccordingtosesamestreet/film.html

This film was remarkable! The film follows U.S. Sesame Street producers to
Bangladesh, Kosovo and South Africa. They set up 'workshops' where this
ICONIC American TV show metamorphosizes to become a local cultural
space to create social consciousness! The U.S. produces are very cultural
sensitive and collaborate with the local producers--- the end result for each
country highlight Jim Henson’s artistry but incorporate indigenous songs,
puppets and curricula ---the film highlights cultural, political and production
challenges.
