A March 8 Bloomberg article about advertisers fleeing Rush Limbaugh's show in the wake of his misogynistic attacks on Sandra Fluke reported that “of the 69 commercial spots” aired during the March 7 edition of Limbaugh's show, “more than half were public-service announcements, according to data collected by Media Matters for America.” Bloomberg further reported that the American Heart Association has “said it would ask WABC to stop running the unpaid announcements.”

From the March 8 Bloomberg article:

The boycott against talk-radio host Rush Limbaugh has some unexpected beneficiaries: non-profits getting more ad time on his show.

The United Negro College Fund, Big Brothers Big Sisters and the American Heart Association are among the organizations that had ads air yesterday during Limbaugh's program, the biggest U.S. talk show, on WABC-AM in New York.

Of the 69 commercial spots on the three-hour show, more than half were public-service announcements, according to data collected by Media Matters for America, a Washington-based non- profit whose mission is to fight “conservative misinformation.” Its research found none on March 1, the day after Limbaugh made his controversial comments about law student Sandra Fluke.

“Those are free,” said Angelo Carusone, campaign director for Media Matters, which has fanned Limbaugh opposition. “It's a sign the boycott is working.”

The American Heart Association said it would ask WABC to stop running the unpaid announcements.

“It is our practice to be a content-sensitive advertiser, and in light of the current controversy, we will be asking WABC to no longer utilize these unpaid PSAs,” Matthew Bannister, executive vice president of communications at the Dallas-based heart association, said in an e-mail.
