What is "alpha-bits"

Alpha-Bits, also known as Frosted Alpha-Bits, is a breakfast cereal made by Post Foods, which contains frosted alphabet-shaped corn cereal bits. Post Cereals also started producing Marshmallow Alpha-Bits in 1990.

Alpha-Bits cereal was invented by a father of seven named Thomas M. Quigley who worked for Post Cereals. The cereal was introduced in 1958, and was taken off the market in 2006. However, Alpha-Bits reappeared for sale in January 2008 with a new formulation, touting "0% Sugar!" as a "Limited Edition" cereal. The old recipe was reintroduced later in 2008.
