You can observe that an objective unbiased media source in any realm with a biased and obfuscated view of reality would do less well relative to one that catered to that biased and obfuscated view of reality, which is why media sources even in the modern age are localised and tailored to the audiences which they are aimed at, prejudices, unfounded beliefs and all like MEMRI in the middle east, christian fundamentalist media like WND, etc. If you expand the scope of enquiry to all of possible human history you can very easily imagine that the media sources which would and have historically done best in the more ignorant periods thereof are obscenely biased and not at all "the best content".
If you think that BBC / NY times / WaPo ad et al are not guilty of the exact same kind of thing merely from a different perspective, well that's quaint and charming, but simply completely inaccurate. Nobody has the full story, everybody is wrong, and putting together the puzzle pieces on any issue requires extensive survey of a broad variety of perspectives and sources, and even then, you're going to fall victim to your own biases and simply become another part of the tapestry to boot.
There is no winning. There's just losing less badly.
