This is the 10's, not the 50's. PBS is about 40 years past any particular relevance as a broadcasting entity. Besides, we don't have "broadcasting" anymore, everything is streamed through cable and satellite. Even local stations.
Frankly, Sesame Street should get out of its victim mindset and tell PBS to take a hike and get its own network. It WOULD be more profitable through its corporate entity that would pretty much guarantee double its current programming, with no advertising (just like PBS), and actually reach more people, especially the lower income people.
BUT...it's not about Sesame Street, because if it were, then there would be no question. It's about maintaining a non-accountable, socialist/progressive entity that is subsidized by the public. THAT crap doesn't deserve the pixels on any screen. It's a pity that they have to take the Sesame St. crowd to cry when it's just a matter of shifting financial accountability.
