Under his leadership, Mars built the world’s largest candy company. After Milky Way’s and M&M’s success, he began to diversify the company’s production and introduced packaged pet foods to the British market. He also adopted a revolutionary method of processing rice which he used to create Uncle Ben’s. By the early 1970s, his candy business amounted to about $200 million in the United States with an additional $55 million in Britain. Of the ten top selling candy bars in the United States, five were sold by Mars (including Snickers at #1).
