http://theweek.com/article/index/225443/has-rush-limbaugh-killed-all-right-wing-radio . Late last week, the liberal website Media Matters posted a list of 51 sponsors who have purportedly withdrawn their advertising from Rush Limbaugh's nationally syndicated radio show because of his remarks about Georgetown law student Sandra Fluke. But a new memo from Clear Channel's Premier Networks, which distributes Limbaugh's show, suggests that those numbers are just the tip of the iceberg. Premier is reportedly informing its stations that 98 major advertisers including carmakers, insurance companies, and fast-food chains want off not just Limbaugh's show but also those of other "offensive or controversial" talkers like Mark Levin, Michael Savage, Glenn Beck, and Sean Hannity. Is it possible that Limbaugh's latest intemperate rant will "kill" the right-wing talk radio genre he helped pioneer?
