From Media Matters:
As part of the continuing exodus of advertisers from The Rush Limbaugh Show, Arby's and Proactiv both confirmed they will no longer run ads during Rush Limbaugh's show. Ads from both advertisers recently started running during Limbaugh's program.
While Arby's noted that they "do not buy ads on national radio programs," the company confirmed on Twitter that its ads would no longer run during Limbaugh's show, advising that it is taking "the necessary steps to discontinue advertising during this show".
And, as JMG notes, the Wingnuts are NOT happy...
