Both Adobe and Yahoo! Have colluded to show contextually relevant Ads with PDF files reports New.com. They state "Yahoo and Adobe are bringing pay-per-click ads to Adobe's Portable Document Format so that publishers can serve up ads inside PDFs distributed on Web sites and over e-mail that are contextually relevant to the content."
This move would allow the publishers to share the revenue with the advertisers, "Publishers upload their PDF content into Yahoo's ad serving system and then monitor the performance through Yahoo's system. Publishers take a cut of the revenue from each click on the ads and Yahoo will split its share of the revenue per click with Adobe."
According to Josh Jacobs, vice president of publisher solutions at Yahoo "The service gives PDF publishers access to Yahoo's network of advertisers and allows them to make money off the content without having their own sales force or having to do the ad insertion themselves."
A couple of publishers have already got on rolling with the beta "Publishers participating in the beta include IDG's InfoWorld, which moved to a Web-only format earlier this year, as well as Wired, Pearson's Education, Meredith Corporation and Reed Elsevier."
