This is assuming all reach is equal. Number of outlets seems like an incomplete picture to me where the number of people reached seems more important. Is a more

  That's a good point, though I think it's unlikely that 5% of the sites and 95% of the sites both make up ~50% of impressions each. But to your point, we don't know unless we know, and my assumption could be totally wrong.

    Well there's two things we have to consider: 1) Pareto: where there's a power law based distribution. So it is possible that 5% of sites have more than 50% of impact. This just means it isn't out of the bounds of possibilities. But we'd have to dig deeper into which sites garner the majority of eyes (though we'd expect a power law in this). 2) Left learning areas tend to be more population dense. Of course with these two considerations we haven't really made any conclusions. I just want to point out that a small number of sites can reasonably hold the majority of viewership. Which sites those are and which bias they entail, that requires a real analysis. We've just stated that the conjecture isn't impossible.
