Object: Pop Tarts

Post adapted its process for enclosing food in foil to keep it fresh without spoiling—first used for dog food—to its new toaster-prepared breakfast food. Intended to complement its cold cereals, Post announced its new product in 1963 to the press, giving them the name "Country Squares".

Because Post had revealed Country Squares before it was ready, Post's biggest competitor, Kellogg, was able to develop its own version in six months. The product, advertised by an animated, anthropomorphic toaster named Milton, became so popular that Kellogg could not keep up with demand.

Originally not frosted when first introduced in 1964, it was later determined that frosting could withstand the toaster, and the first frosted Pop-Tarts were officially released in 1967. The first Pop-Tarts came out in four different flavors: strawberry, blueberry, brown sugar cinnamon, and apple currant. Today, there is a wide variety of Pop-Tart flavors, including Chocolate Chip, S'Mores, Raspberry, and French Toast.

Pop-Tarts come in 29 flavors.
