As you can see, big data has tremendous economic value - so much, in fact, that the New York Times once compared it favorably to gold. Consider Amazon's patented technique called the " Anticipatory Shipping Model." When Amazon predicts that you're going to buy something (like how Target predicts when women are going to deliver their babies), they can ship that item to a warehouse near you, so that when you ultimately buy it, they'll get to you quickly and cheaply. Predicting what you want to buy goes far beyond just recommended purchases, though. Using the pattern that it's found, Amazon could suggest you buy jelly. Then, say you buy peanut butter and bread off Amazon. For instance, suppose Amazon noticed that millions of customers buy peanut butter, jelly, and bread together. Amazon makes these recommendations by finding patterns in past customers' purchases. Amazon can even use the words you highlight on the Kindle to predict what you're going to buy. Based on your purchasing history, Amazon can bombard you with recommendations - look no further than the " Inspired by Your Browsing History" or "Customers Who Bought This Item Also Bought" sections you see around Amazon. There are plenty of other ways Amazon uses its data about you to make a buck. That'll hook customers on Amazon and get them to pay more for the less-common things they'll buy down the road. The idea is that most people will just search for the most common products (which will end up being cheaper on Amazon), so they'll start to assume that Amazon has the best prices overall. Through this process, one useful strategy Amazon has found is to undercut their competitors on popular products but actually raise the prices on uncommon products, such as by discounting bestsellers while jacking up prices on obscure books. This way they can ensure their prices are always competitive and squeeze out ever more profit. With all this data, Amazon analyzes customers' shopping patterns, competitors' prices, profit margins, inventory, and a dizzying array of other factors every 10 minutes to choose new prices for its products. If you put all that data on 500-gigabyte hard drives and stacked them up, the pile of hard drives would be over eight times as tall as Mount Everest.
