Archibald Clark "Arch" West (September 8, 1914 – September 20, 2011) was a marketing executive credited with the development of Doritos, a brand of seasoned tortilla chips. The successful snack food was marketed as an alternative to the more traditional potato chips. Doritos are now Frito-Lay's second best-selling item, bested only by Lay's Potato Chips. An estimated five billion dollars in Doritos are sold every year worldwide.
