Yet, these broadcasters get major amounts of funding from big corporate and legacy foundations and often that “news” or “educational” programming goes against the interests of their sponsors. A prime example is Wells Fargo, giving millions of dollars to these broadcasters from the millions of fraudulent accounts they opened.
At what point can this influence their programing? As it is, tax payer funding is not the majority source any longer and you get all your commercials at the beginning and end of these shows - so the end result is exactly the same as if they were producing Dr. Who, NOVA, PBS NEWSHOUR, or Frontline:Syria. Frontline:Syria looks more like MSNBC and CNN specials now because of today’s technology then ever before.
Your public broadcasters are as beholden to capitalism as the rest of them, they just disguise it better because they target more educated folk.
