Mars knows chocolate sales are nothing to snicker at. The company makes such worldwide favorites as M&M's, Snickers, and the Mars bar. Its other confections include 3 Musketeers, Dove, Milky Way, Skittles, Twix, and Starburst candy; Combos and Kudos snacks; Uncle Ben's rice; and pet food under the names Pedigree, Sheba, and Whiskas. It also owns the world's largest chewing gum maker, the Wm. Wrigley Jr. Company. The Mars family (including siblings and retired company CEO Forrest Mars Jr., chairman John Franklyn Mars, and VP Jacqueline Badger Mars) owns the highly secretive firm, making the family one of the richest in the US.
