Today marks 45 years since Sesame Street first came on television, spawning a resurgence of education children's programming in the U.S.

Fox News Radio's Eben Brown reports:

Three generations of American children started their day on Sesame Street...

(Sesame Street Theme) "Sunny day, sweeping the clouds away..."

...can you count the years it's been on TV?

(Sesame Street clip) "One, two, three, four, five, six, seven, eight, nine, ten, eleven, twelve."

Actually it's 45... 

(Count von Count)  "(Laughing) Ah! Ah! Ah!"

First airing in 1969 with the help of Jim Henson's Muppets...

(Big Bird and Snuffleupagus) "Welcome to Sesame Street! Hi! / Hi! Yeah, I'm glad you're here!"

It spawned cultural institutions....

(Cookie Monster) "Cookie! Nom-nom-nom..."

...and marketing gold...

(Elmo) "Elmo's world! (Laughter)."

All while teaching kids about numbers, letters, and feelings. It changes its style for the times...

(New Sesame Street theme) "How to get to Sesame Street!"

...but, never its message.
