SF ads

Microsoft's Virtual Earth 3D, announced on Monday, allows advertisers to buy banner ads that float above buildings in photorealistic environments. The application, which downloads into a browser, melds together Virtual Earth's 3D features and Microsoft map and local search. In this screen shot, Zip Realty ads appear on virtual billboards in downtown San Francisco near AT&T baseball park.
