In the early 70s Sesame Street was created with an eye towards educating poor, inner-city children for free, and became a massive hit with all children. In 2016, faced with going off the air forever after facing conservative efforts to destroy public broadcasting since basically its beginning, new episodes became a timed exclusive for premium cable network HBO. In 2022 HBO Max, newly merged with and taken over by reality TV channel Discovery, removed Sesame Street episodes and spin-offs from streaming as a tax write-off and scheme to avoid paying residuals.
Sesame Street's official YouTube channel is uploading the episodes for free, btw. A lot of creators are rebelling against this bullshit.
As always, America, PBS has you and your kids' backs.
I also want to put in a plug for the American Archive of Public Broadcasting, spearheaded by GBH in Boston to preserve and make available public funded programming from around the country. More than 7000 public television and radio programs are available to stream through the website, with more than 40000 hours of programming archived and available to researchers and educators through the Library of Congress and GBH itself.
I recognize that not everyone has the means, but if you can, find your local PBS and/or NPR affiliate(s) and give them money! Most of their money actually comes from members and not from the government, so YOU can actually do a lot to keep the lights on and keep the programs you think they should have on the air. At my station at least, you can make a single donation of any size or start a sustaining membership of at least $5/mo., and if you are a sustaining member it also automatically includes a PBS All Access pass (aka the PBS streaming service).
So yes, PBS is technically free, but only because of the support of other members with the means to donate! If that's you, please do what you can!
