As advertisers abandon Glen Beck, will Fox pull his plug?

Can Fox News Channel's Glen Beck survive the desertion of his corporate advertisers? After watching this video clip of him encouraging a guest to argue that the only way to save America is for Osama bin Laden to detonate a major weapon here in the U.S., it made me wonder whether any of the advertisers had actually watched Beck before they bought advertisements.

The list of those former advertisers is growing. For the moment, it includes GMAC Financial Services, ConAgra Foods (CAG), Procter & Gamble (PG), Progressive Insurance (PGR), Geico, Sanofi Adventis (SNY), Roche Holding (RHHBY), Radio Shack (RSH), Men's Warehouse, Lawyers.com, and Sargento.
