Here, I'll do you one better. I'll show you some very simple ways as to why Beck won't survive for long and prove how there is absolutely no way that Beck hasn't lost serious ad revenue:
He's being put as a headliner with other prominent figures of FOX.

When you have one program losing viewers and another which is going strong, networks usually try to remedy the situation by putting a weak show behind a popular one so as not to lose potential sponsors. That's pretty sound business logic only that the problem in not Beck losing viewers. It's Beck losing major sponsors. When you start losing Apple, Progressive, Best Buy etc. it's safe to say that it's the result of 3 possible issues:
A) Companies don't want to be associated with you
B) Your message is too extreme
C) You're boring.
Right off the bat we can scratch C. Beck isn't boring. If he were, he wouldn't have 2-3 million viewers. So what is the issue? Well what company wants to be associated with the guy who calls the President a racist? What company wants to be associated with a guy who has predicted the end of the world? You ever wonder why people like Ron Paul have trouble getting corporations to support him even though he's probably the most free market representative of congress? Is because nobody wants to be associated with the guy who wants to remove the US from the UN. It's not the few parts he gets right. It's how extreme he is.
Now, as far as Beck losing revenue is concerned, I'll show you how:

What a network can charge for ads is not dictated by the actual number of viewers but by the demographics of the people in the audience. If Beck's demographic is made up primarily of people in between the 18-49 groups, he would be able to charge more per ad than somebody who has their audience divided amongst different demographics. Don't get me wrong, a loss of 1/3rd of your viewers is clearly a problem but it's not as big a problem as losing 200 sponsors. Corporations tend to look at each other for where to spend their ad ressource. When you have not one but dozens of car companies, insurance companies and electronics retailers pulling their money out of your show, that sends a strong signal for others to do the same.
So how is Beck losing revenue? Well it's simple, the fact that he now has to sell ad space to people who can't afford the rates you'd charge people like Walmart or Coca-Cola means a giant loss in revenue. As it's impossible to tell just how much one can only say that it's substantial. There's no way that it can't be. Beck can't charge them the same rates he would to transnational corporations and he's losing new sponsors with every ridiculous comment and assertion he makes. He's essentially paying
them to stay on.
