theodp (442580) writes "A newly-granted Google patent on Dynamic Pricing of Electronic Content describes how information gleaned from your search history and social networking activity can be used against you by providing tell-tale clues for your propensity to pay jacked-up prices to 'reconsume' electronic content, such as 'watching a video recording, reading an electronic book, playing a game, or listening to an audio recording.' The patent is illustrated with drawings showing how some individuals can be convinced to pay 4x what others will be charged for the same item. From the patent: 'According to one innovative aspect of the subject matter described by this specification, a system may use this information to tailor the price that is offered to the particular user to repurchase the particular item of electronic content. By not applying discounts for users that may, in relation to a typical user, be more inclined to repurchase a particular product, profits may increase.' Hey, wasn't this kind of dynamic pricing once considered evil?"
