Marketers have vastly more information about potential consumers than ever before. Every time you use a loyalty card you surrender personal information. Every time you do a Google search or hit the “like” button on Facebook, you surrender yet more. Google and Facebook protect personal privacy, but they also make money by selling generic information to advertisers. Professional data-miners use electronic data to create a detailed picture of what you have bought in the past (“history sniffing”) and how you bought it (“behaviour sniffing”). They can then draw your attention to products they think you might want to buy in the future. Smartphones can tell you that there is a shop nearby that stocks just the thing you have been looking for.

And consumers are learning more and more about marketers.
