Skippy was first used as a trademark for peanut butter by the Rosefield Packing Co., Ltd., of Alameda, California in 1933. Percy Crosby, creator of the “Skippy” comic strip (1923), who trademarked the name in 1925, had the trademark invalidated in 1934, but Rosefield persisted, succeeding after the passage in 1946 of the Lanham Act. In 1955 he sold the brand to Best Foods. Its successor companies, most recently Unilever and Hormel, claim rights to the trademark over the objection of Crosby’s heirs, and there has been much litigation on this point over the decades, some of which has continued into the 2000s. It is the best-selling brand of peanut butter in China.
Skippy comes in many different sizes, including a 4-pound (1.8 kg) jar, known as the “Family Jar”. In late 2000, Skippy reduced their standard jar size from 18 ounces (510 g) to 16.3 ounces (460 g) by adding a “dimple” in the bottom of the jar while retaining the jar’s height and diameter.
