My point would be that by it's nature, regardless of content, NPR appeals to a different set of listeners than Fox News does. The useful comparison would be between NPR and talk radio, which seems easy: there's a lot of conservative talk radio.
I don’t understand what you mean by saying that NPR appeals to different group of listeners “regardless of content”, especially as you later observe existence of conservative talk radio. NPR and conservative talk radio appeal to different groups of listeners, but what else make it so, other than the content? Similarly, what makes Fox News appeal to non-whites more than NPR, other than the content?
Maybe! If you think conservative talk radio has more diverse appeal than Fox News, that's an argument. I'm just bristling at comparing NPR to cable news of any sort.
Fox’s viewership is older and whiter than NPR’s. But Fox’s popularity means that even Black Democrats are much more likely to watch Fox than to listen to NPR (or read the NYT): https://www.pewresearch.org/journalism/2020/03/11/black-and-.... About 1/3 of Black democrats get political news from Fox. Just 10% get political news from NPR.
> One way that black Democrats break out of the media bubble is that roughly a third (36%) get political news from Fox News, which, according to the Center’s survey data, has an audience that leans to the right politically. That contrasts sharply with the 17% of white Democrats who get political news from Fox.
> In using sources for political news, black Democrats are also more inclined to turn to ABC News (53%) and CBS News (46%) than white Democrats (35% and 34%, respectively). White Democrats, however, are much more inclined to get political news from The New York Times (39%) than their black counterparts (12%). The same pattern holds for NPR (43% vs. 10%) and The Washington Post (32% vs. 13%).
