Chex

Chex is an American brand of breakfast cereal currently manufactured by General Mills. It was originally known as Shredded Ralston, first produced in 1936 and owned by Ralston Purina of St. Louis, Missouri, then later renamed Chex in 1950. The Chex brand went with corporate spinoff Ralcorp in 1994 and was then sold to General Mills in 1997. Rival cereal company Kellogg's has the rights to the Chex brand in South Korea and Singapore.
