That's an awful lot of supposing, even for me. While I see your point, it's inconceivable that there is a marketable audience. Hell, I can't even get 24/7 baseball without paying for it myself. Without that audience, there would be no broadcasting system to support.
It's not supposing at all,
Allbiz.
Programming itself requires some POV and every POV is biased.
Understand I like PBS, but it is not unreasonable to object to the government getting involved in the arts and entertainment.
Of course, PBS doesn't really get as much money from the government as most people think..
Last information I got suggested that the FEDs fund about 15% of their overall budget.
The other 85% comes, mostly, from various foundations who fund programs that they like.
Damned little of it (my guess..I cannot find hard numbers) actually comes from the viewing public.
