I assume that Sesame Street must have received a significant amount of public funding over the years, from governments, while it was being broadcast on public television.
As such, it seems like there should be some kind of legal obligation to keep it public.
This is one of my pet peeves — when a project receives significant public funding and then it is just essentially reverted into an entirely private benefit. It shows up in a number of domains of activities (telecommunications, research grants, and so forth) and always seems to me that there should be significant legal consequences for not maintaining public benefit or access in some way.
I might be wrong in this particular case though — maybe the public funding was always indirect, through the broadcasters?
