Rush Limbaugh posted an interesting pair of questions at his web site yesterday: "How can CNN still be on the air with no audience? How can MSNBC have been on the air with no audience? In the old days, they're gone, kaput. Something else is tried. But they stay. And they double down on what they're doing that's losing audience."
A large part of the answer, as I noted on March 30, is that those two networks apparently have suffered very little financially as they have lost audience. That's because, as is apparently the case with most of the major cable channels, their primary source of revenue comes from "subscriptions," also referred to as "carriage fees" or "license fee revenues." In plain English, cable channels get paid a great deal of money even if nobody watches them, and don't benefit as much as would be expected when their audience grows.
