The American Companies With The Most Valuable Brands: "24/7 Wall St. has done an analysis of the largest companies in the United States based on the size of their portfolios of major consumer brands. Many of these brands are worth billions of dollars if brand valuation firms are correct. All certainly generate tremendous sales. The Procter & Gamble brand portfolio creates more than $40 billion in revenue each year. P&G has a market value of $186 billion. Coca-Cola, another company on the list, has a market value of $155 billion. The success of these corporations is based almost entirely on their brands. Most of the corporations on this list have flagship products that are decades old and some were first introduced before 1900. None of the companies on the list is a one-trick pony. Brand diversification has been one of the most successful American business strategies over the last several decades. Mars has a large array of chocolate and pet food products. Kellogg has dozens of cereals. Each company used manufacturing, marketing, and distribution expertise as leverage for commodities purchases and product placements in retail outlets."
