[indubitable]

I do not think there's very much diversity of bias in today's publications. It mostly breaks down into a very binary partisan split. You have 'liberal outlets' that mostly sound identical and 'conservative outlets' that mostly sound identical.

In the past there was less child-like black and white conflict, but there was vastly more disagreement on views and papers willing to publish things that fell outside the expected grain. The New York Times was a real leader in this regard. My favorite example is probably from an article from 1920. The NYT ran a featured editorial arguing that rockets could not actually work in a vacuum, like space, since 'there would be nothing for its thrust to push back against.'

They were obviously very wrong, but nonetheless were willing to consider views that ran against the grain even for the time. And that is a good thing. Many of the things they were right on were also equally 'out there' at some point, but I'm not mentioning those as we have the bias of 'well that really happened' so the truth doesn't seem as bizarre as it really is.

The problem we have now a days is that the media has become so collusive and incestuous that they rarely publicly disagree, again beyond the partisan split which I can only describe as child-like. And, in my opinion, this is likely intentionally done under a belief that having a unified front would increase their apparent integrity or confidence. Collusive groups like JournoList turned CabaList would work as some evidence towards this. However, at the same time it also completely destroys any notion of competence when everybody gets something so completely wrong. A very recent example of this would be the so-called 'sonic weapons' used 'against' US diplomats in Cuba. In spite of the media going into a unified frenzy of speculation and finger pointing, literally no major outlet took the logical, even if outsider, position that this probably was not even an attack in the first place. And now that it seems like that it indeed was not, it leaves the entire media system looking like a joke. Even when there are only two options (is a weapon, or not a weapon), nobody managed to get it right. That's sadly impressive and again something that was far less frequent an occasion in the past.
