"Imagine this: You're strolling virtually through your favorite Google Street View destination, when suddenly you notice an animated ad on one of the billboards beside the street. \"Buy product X,\" it beckons you, replacing the obsolete ad that was originally on the billboard when the Google Street View car took the picture. \nThis might very well turn into a reality. Google has been granted a patent named \"Claiming Real Estate in Panoramic or 3D Mapping Environments for Advertising,\" detailing \"techniques for identifying groups of features in an online geographic view of a real property and replacing and/or augmenting the groups of features with advertisement.\" \nThe idea is ingenious, really. Most of those obsolete ads on billboards serve very little purpose in the virtual world of Street View, but if one could replace them with up-to-date advertisements, they could be another source of income for the giant from Mountain View. \nOf course, there's a jungle of legal obstacles that Google would have to solve before actually going through with this. Who owns the virtual billboards? And what about the companies who paid for the original ads on them? ReadWriteWeb points out some of the possible issues, but one thing is certain: Google's strategy of amassing virtual real estate will pay off one way or another."^^<http://www.w3.org/2001/XMLSchema#string>
