Conagra Brands, Inc.
A maker of pantry and freezer staples, Conagra Brands sells beloved American food brands like Slim Jim, Duncan Hines, Birds Eye, Marie Callender's, and Reddi-wip to shoppers and restaurants. It began in 1919 as Nebraska Consolidated Mills, a merger of four grain mills, taking its name in 1971 from Latin words for "consolidated" and "agriculture." Fun fact: Duncan Hines was a real traveling salesman who reviewed restaurants before his name became cake mix.
