Best put on your glasses and try again:

You could buy NBC News, but then what would you have? A white elephant operation whose dwindling viewers are older and either share its biases or don't care

Maybe you are missing the point here. The comment isn't about NBC news it's about what would happen if NBC were purchased by a conservative organization, which is the very premise of the article.

His claim is that (after a purchase) NBC would then be a media outlet that's value is far less then it's upkeep because it would only be viewed by a aging and dwindling demographic.

Do you think that the author is saying that NBC has an aging and dwindling viewership, and it's demographics would remain exactly the same after being purchased by a conservative group? That doesn't make any sense.

Is he suggesting that Conservatives are an aging and dwindling group? Perhaps not but it's a very popular liberal meme isn't it?
