With the world’s largest consumer market, the United States has long been an incubator for globe-leading companies. Brands like Coca-Cola and Ford are as American as the Liberty Bell and baseball. But some of the iconic companies that, 50 years ago, topped the Fortune 500 list have since fallen behind overseas competitors. The recent financial crisis nearly swallowed up corporate stalwarts like General Motors and Chrysler, which filed for bankruptcy and needed government bailouts. Other corporate icons such as Anheuser-Busch were bought by foreign competitors. But, as some American business giants fade, others are rising. And a new batch of U.S. businesses are inventing the young social media industry. Here’s a look at some of 1960s’ leading companies, according to the Fortune 500 list, and how they’re faring now. It includes Wal-Mart, founded in 1962, the current top Fortune 500 company.
