The first patent for a non-stick cooking spray was issued in 1957. Arthur Meyerhoff, Sr. and Leon Rubin who started PAM^® Products, Inc. marketed the product in 1959. In 1961, Leon Rubin invented his own non-stick cooking spray. Along with Arthur Meyerhoff, the two men founded Gibralter Industries to market this new PAM^® All Natural Cooking Spray. PAM^® actually stands for a Product of Arthur Meyerhoff.

In the early 60s, a loyal user group was established through the introduction of PAM^® on local Chicago TV cooking shows. Carmelita Pope, a well-known Chicago personality, endorsed PAM^® and demonstrated its many uses.

PAM^® quickly became a household word. The easy-to-use spray was widely regarded as the perfect substitute for sautéing with butter, margarine or oils. With PAM^®'s convenient no-stick formula, there was no longer any need to grease cooking or baking equipment with products high in fat.

In 1971, Gibralter Industries merged with American Home Products, Inc, who in turn, gained title to the patent for PAM^®. The company's Boyle Midway Division took over the product's marketing and distribution responsibilities. In 1990, American Home Foods assumed responsibility for the brand. In November 1996, AHF was acquired by Hicks, Muse, Tate and Furst Inc., and C. Dean Metropoulos and Company. This became International Home Foods, Inc. In 2000, PAM^® was acquired by ConAgra Foods, Inc.

PAM^® has continued to evolve with the times. In 1985, PAM^® Butter Flavor was introduced and one year later, PAM^® Olive Oil joined the product line. The 1990's showed the switch to Canola Oil, the lowest in saturated fats of all popular vegetable oils, for both Original and Butter Flavor PAM^®.

In Fall 2003 PAM^® introduced yet another convenient spray PAM^® Baking which combines the unbeatable no-stick power of PAM^® with real flour. In Summer 2004 PAM^® followed up with PAM^® Grilling which is specially formulated for no-stick at higher temperatures.

Today, PAM^® remains America’s favorite no-stick spray. Through innovation and product introductions PAM^® continues to be popular in households throughout the country and in fine restaurants everywhere.
