Buffett, one of the world’s richest people and most accomplished investors, took control of Berkshire Hathaway in 1965 when it was a textiles manufacturer. He turned the company into a conglomerate by finding other businesses and stocks to buy that were selling for less than they were worth.

Buffett said he will step down as CEO of Berkshire Hathaway, ending a 60-year run where he became an influential and iconic part of the U.S. economy.

Tens of thousands of people are in Omaha, Nebraska, to attend the annual shareholder weekend for billionaire Warren Buffett's Berkshire Hathaway .
