Earn with Adobe PDF Ads

Checking the latest at the Adobe Labs, I saw this income generating tool from Adobe PDF. Ads for Adobe PDF, which is powered by Yahoo!, allows to generate income with your published PDF documents. It is currently in its beta version and is only limited to some qualified publisher.

Ads for Adobe PDF is a new opt-in service that enables publishers to monetize their PDF content through advertising. The advertising service, powered by Yahoo!, automatically matches and displays dynamic, contextual ads in Adobe Reader and Adobe Acrobat when a user views the PDF. Publishers that sign up to participate in this program are eligible to be paid for valid clicks on ads. In this unique advertising relationship, Yahoo! helps connect advertisers from its extensive network of online advertisers with publishers that are distributing content through Adobe PDFs. Yahoo! will incorporate this new advertising inventory into its portfolio of online advertising opportunities.
