What snack food did the U.S. Food and Drug Administration (FDA) legally bar using “chips” as a description for its product?
The picture I selected gives it away, but it’s somewhat interesting. The container tubes for Pringles currently label the product as “potato crisps.” While Pringles are 
often thought of like potato chips, technically, their parent company may just refer to them as “crisps.”
Pringles were initially known as “Pringles Newfangled Potato Chips”; however, other snack producers objected to the brand’s use of the term potato chip to describe Pringles. The FDA ruled in 1975 that Pringles could only use the word “chip” in their product name in the following phrase: “potato chips are made from dried potatoes.”
Sounds yummy. Rather than do this, the company began referring to Pringles as potato “crisps” rather than potato chips.
Personally, I call them chips.
