Update. More advertisers have pulled their ads from Fox News Channel's Glenn Beck Program. Ally Bank, Allergan, Broadview Security, CVS, Best Buy, Travelocity, Re-Bath, and Wal-Mart Stores have followed a dozen other companies including Geico, which said last week it was pulling its financial support of the conservative commentator.

Here's last week's post about Geico's decision.

Geico has pulled its iconic car-insurance advertisements from the Glenn Beck Program, which broadcasts on the Fox News Channel cable network, the African-American advocacy organization ColorofChange.org said Wednesday.

The insurer, the ads for which feature dispirited, talking cavemen and a chatty gecko with a cockney accent, has joined a growing list of advertisers who are abandoning Beck, a conservative commentator with a penchant for petulance and over-the-top criticism of President Barack Obama and other Democratic leaders.

Earlier this month, Geico instructed its ad buyer "to redistribute its inventory of rotational spots" to other Fox-TV programs, ColorofChange said in a statement, citing an email received from Geico. "As of August 4, Geico no longer runs any paid advertising spots during Mr. Beck's program," the email read.

Among other sponsors who have pulled their ads from Beck's show are household products companies Procter & Gamble and SC Johnson, and another insurer, Progressive Insurance, ColorofChange said. Remaining sponsors include UPS, Oreck, and the Cancer Treatment Centers of America.The organization has been urging advertisers to boycott Beck's show, which airs at 5 p.m. weeknights, for what it calls Beck's hateful rhetoric, including comments Beck made about Obama being '"a racist" who "has a deep-seated hatred for white people."'

The Fox News Channel is generally known for its conservative stance and its criticism of liberal leaders throughout the government, including House Speaker Nancy Pelosi and Senate Majority Leader Harry Reid. The network is a subsidiary of News Corp. (NWS), run by media-mogul Rupert Murdoch. News Corp.'s other holdings include The Wall Street Journal, a publication renowned for its conservative editorial stances.

ColorofChange founder James Rucker announced Geico's decision in a column published on HuffingtonPost.com on Wednesday afternoon.

ColorofChange is hoping to enlist more people in its effort to convince advertisers to pull ads from Beck's show. To date, it said, 75,000 members of the organization have signed a petition asking executives at specific companies to drop their support for the show.

In his column today, Rucker asked supporters outside the organization to also sign the petition.
