A series of online ads for Barack Obama's campaign have been pulled by the Democratic National Committee (DNC) from Rock radio stations' Web sites, due to their appearance next to racier content. According to ClickZ, the ads were bought by the DNC and appeared briefly on a number of Rock stations' sites, primarily Clear Channel stations. However, when media firm Centro noticed the ads were appearing next to "Thong Of The Day" and "Chicks On Toilets," they were pulled from the sites.

"The content on these sites is clearly objectionable and the ads should not have been displayed there," Centro CEO Shawn Riegsecker told ClickZ News. "As soon as we were alerted to this issue, we removed the ads immediately. The DNC and Obama for America maintain very high editorial and content standards of where their advertising is displayed and we should not have placed an ad there."

Among the stations whose sites featured the Obama ads were WQBZ (Q106)/Macon, GA and WACL (98Rock)/Harrisonburg, VA. The ads were aimed mainly at stations in "battleground states" including Florida and Ohio, as well as Georgia and Virginia.
