Wikipedia: Jolly Rancher
Jolly Rancher is a brand of sweet, somewhat tangy or sour/sweet hard candy, gummies, fruit chews, jelly beans, lollipops, gelatin desserts, gum, and sodas. It is currently owned by The Hershey Company. The product was originally produced by the Jolly Rancher Company, founded by Bill Harmsen of Golden, Colorado. The Jolly Rancher Company made ice cream, chocolate and candy sold at several “Ranch Maid Ice Cream” stores in the Denver area. The name was meant to suggest a hospitable, western company.
