In 1972, an executive at Pet Milk (later Pet Incorporated) of St. Louis, Missouri, introduced Heartland Natural Cereal, the first major commercial granola. At almost the same time, the Quaker Oats Company introduced Quaker 100% Natural Granola. Quaker was threatened with legal action by Gentry, and they subsequently changed the name of their product to Harvest Crunch. Within a year, Kellogg's had introduced its "Country Morning" granola cereal and General Mills had introduced its "Nature Valley". In 1974, McKee Baking (later McKee Foods), makers of Little Debbie snack cakes, purchased Sovex. In 1998, the company also acquired the Heartland brand and moved its manufacturing to Collegedale. In 2004, Sovex's name was changed to "Blue Planet Foods".
