Michael Moss, a New York Times reporter who writes about the intersection of food and marketing, recently launched a series of videos that reveal not just how junk food marketers entice us, but also why. In this video, Moss talks of Taco Bell's Doritos Locos Taco: "The reason Doritos Locos have been so successful ... is because they are engineered to target taste buds using the most powerful features known to manufacturers," he says.
