marking the first effort by the firm to expand into fluid milk and ice cream outside the United States. In the same year it also acquired The Southern Oil Company in Manchester, England. National Dairy becomes Kraft In 1969, the firm changed its name from National Dairy to Kraftco Corporation. The reason for the name change was given at the time: "Expansion and innovation have taken us far afield from the regional milk and ice cream business we started with in 1923. Dollar sales of these original products have remained relatively static over the past ten years and, in 1969 accounted for approximately 25% of our sales." At the same time, the firm transferred to Glenview, Illinois, in 1972. In 1976, its name changed to Kraft, Inc. to emphasize the trademark the company had been known for and as a result of the fact that dairy, other than cheese, was now only a minor part of the company's sales. Reorganization also occurred after the name change. Dart merger In 1980, Kraft merged with Dart Industries—makers of the Duracell brand of batteries, Tupperware brand of plastic containers, West Bend brand of home appliances, Wilsonart brand of plastics and Thatcher glass—to form Dart & Kraft. During the 1980s, Dart & Kraft offered mixed results to its shareholders, as new acquisitions in the food business—such as Churny premium cheeses, Lender's Bagels, Frusen Gladje ice cream and Celestial Seasonings tea—slightly offset the lagging nonfood business—Tupperware's decrease in sales and KitchenAid's (acquired soon after the merger) slide in market share—leading Dart & Kraft to spin off its nonfood business (except Duracell batteries) into a new entity (Premark International, Inc.) while changing its name back to Kraft, Inc. Premark was bought by Illinois Tool Works in 1999. In 1988, Kraft sold Duracell to private equity firm Kohlberg Kravis Roberts, who then put it into an initial public offering in 1989. Gillette bought Duracell in 1996, and itself was acquired by Procter and Gamble in 2005. Philip Morris acquisition and merger with General Foods At the end of 1988, Philip Morris Companies purchased Kraft for $12.9 billion. In 1989, Kraft merged with Philip Morris's General Foods unit—makers of Oscar Mayer meats, Maxwell House coffee, Jell-O gelatin, Budget Gourmet frozen dinners, Entenmann's baked goods, Kool-Aid, Crystal Light and Tang powdered beverage mixes, Post Cereals, Shake 'n Bake flavored coatings and numerous other packaged foods—as Kraft General Foods.
