The NutraSweet Company makes and sells NutraSweet, their trademarked brand name for the artificial sweetener aspartame, and Neotame. Despite losing market share in recent years to sucralose, the NutraSweet Company states that its product is used in more than 5,000 products and consumed by some 250 million people worldwide. Aspartame was invented by chemists at G. D. Searle & Company in 1965. Searle was bought by Monsanto in 1985. In March 2000, Monsanto, which was then a subsidiary of the Pharmacia corporation, sold NutraSweet to the private equity firm J.W. Childs.
