PAM is a cooking spray currently owned and distributed by ConAgra Foods. Its main ingredient is canola oil. PAM was introduced in 1959 by Leon Rubin who, with Arthur Meyerhoff, started PAM Products, Inc. to market the spray. The name PAM is an acronym for Product of Arthur Meyerhoff. In 1971, Gibraltar Industries merged with American Home Products (now Wyeth) and became part of the Boyle-Midway portfolio. When Reckitt & Colman (now Reckitt Benckiser) acquired Boyle-Midway from American Home Products in 1990, PAM became part of the American Home Foods subsidiary. In 1996, AHF was acquired from American Home Products by Hicks, Muse, Tate & Furst and C. Dean Metropoulos & Company, becoming International Home Foods, which in turn was acquired by ConAgra in 2000. PAM is marketed in various flavors, such as butter and olive oil, meant to impart the flavor of cooking with those ingredients. Flavors such as lemon or garlic are also offered. PAM also markets high-temperature sprays
