Google Patents Location-Based Advertising

Here we go, it's Web 3.0, coming to get us. As soon as you sign on, rather than receiving ads for some random company, Google will now advertise a tea shop to you if you're searching for drinks with your Android in the middle of London, or a silk worm factory if you're hanging out in Thailand trying to find a cloth distributor. According to the link above, this also gives power of price arbitration. It will be interesting to see how online companies like Amazon will be affected by this. Of course, a company like Amazon is large enough that they probably won't have troubles, but smaller companies might.
