From an August 23 Associated Press article:

Glenn Beck returns to Fox News Channel after a vacation on Monday with fewer companies willing to advertise on his show than when he left, part of the fallout from calling President Barack Obama a racist.

A total of 33 Fox advertisers, including Walmart, CVS Caremark, Clorox and Sprint, directed that their commercials not air on Beck's show, according to the companies and ColorofChange.org, a group that promotes political action among blacks and launched a campaign to get advertisers to abandon him. That's more than a dozen more than were identified a week ago.

While it's unclear what effect, if any, this will ultimately have on Fox and Beck, it is already making advertisers skittish about hawking their wares within the most opinionated cable TV shows.

The Clorox Co., a former Beck advertiser, now says that “we do not want to be associated with inflammatory speech used by either liberal or conservative talk show hosts.” The maker of bleach and household cleaners said in a statement that is has decided not to advertise on political talk shows.
