The chart is measuring major networks vs fledgling websites, and giving them equal weight. Each one counts as "one". Nothing about audience size, reach, popularity, etc......the Washington Times offsets the one of the AP, the CBS News, CNN, The New Yorker or the NYT?
Think back to 2016 when this shit started getting exposed. Regular people were not looking at the NYT, ABC, NBC, etc as propagandist arms of the left. Now, of course, they've been exposed, and smart people know the deal.
Yes, more conservative sites have emerged, but they had nowhere near the audience, or the trust that the major networks used to have.
If these charts only measured major liberal leaning/centrist networks against conservative leaning networks, aside from FOX, there would be nothing on the conservative side of the charts. Do you think this would be more accurate and fairer than including the fledgling websites is? Why do the conservative sites have relatively tiny audiences as compared to the more liberal ones? Why are there not more conservative major networks if this is what folks prefer?
