I said what I said on the comment I left on the video...
39 years... and all things considered, Elmo's World and whatnot, it is still a great show. And not just in terms of the show itself... look at all the things they accomplished. All those different international versions and that legacy of everyone that's ever worked on it. There has never been a kid;'s show that held this standing, and I doubt there ever will be. I think it stands the test of time, and deserves to be in the same company as the classics, Mr. Rogers, Mickey Mouse Club, and Howdy Doody. And at the same time, it's still around, and it shows no signs of ending any time soon.
That's an accomplishment in and of itself. Did they figure it old last, what, 5 years at best? And here it is, almost 40 years later.... History was made on that day...
