I emailed to a couple of advertisers whose products I use to let them know I will stop buying them because of their support of Glenn Beck's program.
One of the advertisers is Brita, and this is the email response I got.

Dear Ms. Flynn,

This is in response to your recent communication regarding a Clorox Company advertisement. Thank you for bringing this to our attention. We very much appreciate your feedback and vigilance of broadcast television as The Clorox Company remains committed to quality broadcasting. We pride ourselves in being a responsible advertiser and have established strict standards for the selection of television programming. Per our standards, we do not advertise in programs that display exploitive sex or violence; treat ethnic, religious or political groups in a disparaging manner; present facts inaccurately or distort them to blatantly partisan advantage; and treat individuals or groups in a demeaning manner.

We understand that while Glenn Beck was a guest on the program Fox & Friends on 7/28/09, he made the statements that you wrote to us about. After a thorough investigation by our agency partners, we have confirmed that no Clorox Company advertisement aired in the above program where Glenn Beck made the specific comments you referenced. While we've had limited advertisements on the Glenn Beck Program in the past, the programming content at issue would not adhere to our programming standards and furthermore we will continue to rigorously scrutinize these types of shows for participation.

Today's television programming environment is extremely challenging for responsible advertisers. Our programming selections are proprietary and we are not able to share the details of these externally. However, The Clorox Company will continue to exercise special care in all program and station selection. We do not want to support programming that is in conflict with our programming standards.

Thank you again for taking the time to contact us.
