The author of Media Today offers "a trenchant, timely, and troubling account of [retailers'] data-mining, in-store tracking, and predictive analytics" (The Philadelphia Inquirer). By one expert's prediction, within twenty years half of Americans will have body implants that tell retailers how they feel about specific products as they browse their local stores. The notion may be outlandish, but it reflects executives' drive to understand shoppers in the aisles with the same obsessive detail that they track us online. In fact, a hidden surveillance revolution is already taking place inside brick-and-mortar stores, where Americans still do most of their buying. Drawing on his interviews with retail executives, analysis of trade publications, and experiences at insider industry meetings, advertising and digital studies expert Joseph Turow pulls back the curtain on these trends, showing how a new hyper-competitive generation of merchants—including Macy's, Target, and Walmart—is already using data mining, in-store tracking, and predictive analytics to change the way we buy, undermine our privacy, and define our reputations. Eye-opening and timely, Turow's book is essential reading to understand the future of shopping. "Turow shows shopping today to be an exercise in unwitting self-revelation—and not only online."—The Wall Street Journal "Thoroughly researched and clearly presented with detailed evidence and fascinating peeks inside the retail industry. Much of this information is startling and even chilling, particularly when Turow shows how retail data-tracking can enable discrimination and societal stratification."—Publishers Weekly "Revealing . . . Valuable reading for shoppers and retailers alike."—Kirkus Reviews
