Well to be hexact, here's the breakdown.
Sesame Street Unpaved. The name of both the book and the shows.
What happened was that Nickelodeon and the makers of Sesame, CTW or the Children's Television Workshop as they were known back then, made a deal in the late 1990's to own half each of a brand new channel named Noggin. (Nowadays the makers of Sesame Street are known as Sesame Workshop.) Anyway, Noggin grabbed itself a handful of about 70 episodes of the classic Sesame Street from the first twenty years and collectively called the showing Sesame Street Unpaved. Then, a collective textbook spanning the first thirty years of the show was released with the same title.
The shows of Sesame episodes from Season 25 to 29 fall under the category of 1-2-3 Sesame Street aired at 3:30 PM EST and maybe at 5:00 AM EST on Noggin currently.
The episodes from Season 30 and onwards up to the present are aired under the same heading but at 9:30AM EST and 12:30 PM EST.
At the time, SSU airs at 4:00 AM EST only on Mondays but this might change soon.
Hope this helps.
