There is this:

Cable News Guests Were Largely White Men. According to the most recent U.S. Census data, white men make up only 31 percent of the U.S. population. On evening cable news, they represented a much larger percentage of guests — 62 percent of guests on CNN, 60 percent on Fox, and 54 percent on MSNBC.

There is also this:

White Guests Hosted Most Often On Cable News. Fox News had the largest proportion of white guests — 83 percent. African-Americans were the largest non-white group on all networks, representing 19 percent, 10 percent, and 5 percent of guests on MSNBC, Fox, and CNN, respectively

And this is the way it is:

Non-Hispanic White or European America - 63.7 %

Are we arriving at a stage in American history when there's no such thing as universal news programming? Meaning, in our moment, Fox and CNN are not transnational but instead are for white Americans what Univision is for Latin Americans and BET for black Americans.
