Did you know that In 1964 General Mills began marketing Lucky Charms cereal with pink hearts, yellow moons, orange stars, and green clovers. The marshmallow bits (technically referred to as marbits) were invented in 1963 by John Holahan. The cereal is marketed using a leprechaun character named Lucky (L.C. Leprechaun is his full name) that touts his cereal as being "Magically Delicious." Over the years the various shapes and colors of the marshmallow bits in the cereal have undergone many changes.
