sesame street still kickin ass

I just saw online that today is the 40th anniversary of Sesame Street the children’s television show. I thought this was pretty cool because I remember watching this show when I was like 5 years old and thinking it was the greatest thing on earth. I liked all the characters and was compelled by all the stories. Clearly kids of several generations have felt the same way as I did if the show has gained enough support to keep running for 40 years, but I am curious as to what makes this show stick out from the rest for kids? Especially with all the advancement in technology, new generations of cartoons and just all the other options kids have for entertainment in each new decade what has made this show stand the test of time? There has been tons of popular shows and characters throughout the years but the creators of Sesame Street were able to figure out a way to appeal to children no matter what generation the grew up in.
