How to make radio an accurate source of news?

All news reports are inherently biased. Just the fact that something is reported makes in seem more important than things that were not reported. Just the fact that a picture includes something and excludes everything else makes it biased.

Who pays for the news reports? Obviously, reporters are not going to say things that reflect badly on their sponsors. That's why stock advisers on tv never advise to sell, only to buy and hold.

Both are "accurate" representations of history, but from different points of view.
