Olestra was approved by the Food and Drug Administration for use as a food additive in 1996, and was initially used in potato chips under the WOW brand by Frito Lay. In 1998, the first year olestra products were marketed nationally after the FDA's Food Advisory Committee confirmed a judgment it made two years earlier, sales were over $400 million. By 2000, though, sales slowed to $200 million. P&G abandoned attempts to widen the uses of olestra, and sold off its Cincinnati-based factory to Twin Rivers Technologies in February 2002.
