From what I've found, Sharon, some of the sponsors dropped both radio and tv ads.

On a Ron Paul web site, it's being called "Becklash". There's no love lost between Ron Paul supporters and Beck, since Glenn Beck slammed Ron Paul during the primaries.

I found this news release from colorofchange.org from back on August 6.
"Three companies who run ads during Glenn Beck -- NexisLexis-owned Lawyers.com, Proctor & Gamble and Progressive Insurance -- today distanced themselves from Beck. LexisNexis has pulled its advertising from Beck and says it has no plans to advertise on the program in the future. Both Proctor & Gamble and Progressive Insurance called the Beck advertising placements an error that they would correct.

    The decision by the three companies comes as over 45,000 ColorofChange.org members call on advertisers to pull their ads from Glenn Beck after the controversial news host called President Obama a "racist" who "has a deep-seated hatred for white people" on "Fox & Friends" last week.

    "Thank you for bringing this matter to our attention," said John Michaels, Senior Communications Manager at LexisNexis in an email to ColorOfChange.org. "We have suspended further advertising during Mr. Beck's program."
