Adobe and Internet portal Yahoo! have announced an agreement that creates an "Advertising Service For PDF Publishers:"

Adobe Systems Incorporated and Yahoo! Inc. today launched Ads for Adobe PDF Powered by Yahoo!, an opt-in service that enables online commercial publishers to drive new revenue by including timely, contextual ads next to Adobe Portable Document Format (PDF)-based content. The service has the potential to offer readers access to more free content, enhanced with ads that match their interests. Ads for Adobe PDF Powered by Yahoo! is available initially as a beta program.

"By partnering with Yahoo! on this innovative advertising service we are creating opportunities for publishers to build new businesses around unique content that previously was just given away or not available to a mass online audience,” said Rob Tarkoff, senior vice president, Corporate Development at Adobe in a release announcing the partnership, “As advertisers look to touch new audiences, readers can look forward to some exciting Adobe PDF content coming their way."

Quoted in the Wall Street Journal, Kurt Garbe, an entrepreneur in residence in advertising at Adobe said, "Consumers' expectation is that content is free, some content will be sold at premium pricing, but there's a whole bunch of content that can be monetized through ads."
