Ready-to-eat cereal was by far the largest category with dollar sales amounting to about 8.33 billion U.S. dollars in the United States in 2018. The U.S. cereal market is dominated by General Mills and the Kellogg Company. The two competitors went head-to-head over sales of ready-to-eat cereals in 2017. However, among individual brands, store brand cereal still beat out both companies in terms of sales.
In the bread aisle, fresh bread companies such as Grupo Bimbo, which owns Sara Lee and Oroweat among many other brands, and Flowers Foods Bakeries Group dominated the market in 2019. Crusty/hot hearth breads were the most purchased bread type in the United States in 2017, based on retail-tracked sales.
