I'm skeptical that it's a deliberate conspiracy, and this is not a scientific test, but I just checked the following news sites, and not one of them had any related hits for "Ohio" listed on their main pages:

BBC America

Reuters

CNN

Fox News

The New York Times

The Seattle Times

MSNBC

CNBC

Seems a little weird for sure. All of those sources have coverage AFAIK, but one has to dig to see it. I imagine algorithmic content promotion is at least partly a factor. I.e. if people aren't clicking on news about that story as much, it probably falls off the main page. So perhaps it's more like paid corporate Wikipedia shills, except it's click farms to promote other content and get the embarrassing news off of the front page?

That having been said, I know of at least two topics the American press is likely to deliberately downplay or avoid reporting on - solo suicides and certain types of civil unrest - so while I strongly dislike conspiracy theories in general and think it's unlikely in this case, I can't rule out the possibility that this is another one of those topics.

I just loaded up CNN and saw 20 stories before having enough. The worst example being a celebrity pregnancy. I did not note anything about this story. I viewed the mobile website and desktop version.

I can think of a billion things going on right now that are vastly more important than anything about a celebrity pregnancy.
