Chex

Chex is a brand of breakfast cereal currently manufactured by General Mills. It was introduced in 1937 and was originally produced and owned by Ralston Purina of St. Louis, Missouri. The name "Chex" reflects the "checkerboard square" logo of Ralston Purina. The Chex product line was part of the Ralston portion of Ralston Purina, which was spun into Ralcorp in 1994. The product line was sold to General Mills in 1997. For many years, advertisements for the cereal featured the characters from Charles Schulz's Peanuts comic strip.
