News.com's Paul Festa has a report that GuruNet is displaying contextual ads that are autogenerated by Google's AdSense. GuruNet and Google have entered into a revenue sharing-based business arrangement. GuruNet isn't the only one. Today, I met with Michael Yang, CEO and Founder of a new search engine called Become.com. The company, which is less than a year old believes it has built a better mousetrap when it comes to helping shoppers find what they're looking for (more coverage and a podcast interview coming soon). Become.com is also displaying AdSense-based contextual advertising and has entered into a rev-share with Google. Where else will AdSense turn up next?
