What did the world look like before Sesame Street?

November 10, 1969 -- it was a different world. The idea of public broadcasting was new. There were no cable networks yet. The dial only went up to 13.


We forget how much the world has changed since Sesame Street started teaching all Americans to read. According to Virginia Heffernan of The New York Times, the Sesame Street Season 1 has been labeled not suitable for children. She quotes the DVD case: 

These early ‘Sesame Street’ episodes are intended for grown-ups, and may not suit the needs of today’s preschool child.

I'm really curious - those of you who remember the world before Sesame Street: what changed?
