The Virtual Peanut Butter Museum!

In 1946 William T. Young, who served stateside as an officer in the ordnance branch of the U.S. Army during World War II, started his own peanut butter company called Big Top. This company would give birth to the Jif brand in 1958. Jif is made by The J.M. Smucker Company, which purchased the brand from Procter & Gamble in 2001. In 1981, Jif became the largest peanut butter brand in the United States. Sources: Creamy & Crunchy (J. Krampner) and Wikipedia
