Foods are overwhelmingly the most advertised group of all consumer products in the United States. Food products lead in expenditures for network and spot television advertisements, discount coupons, trading stamps, contests, and other forms of premium advertising. In other media-newspapers, magazines, newspaper supplements, billboards, and radio-food advertising expenditures rank near the top. Food manufacturers spend more on advertising than any other manufacturing group, and the Nation's grocery stores rank first among all retailers.
