5. New York: Michael R. Bloomberg
Michael R. Bloomberg is the CEO and co-founder of Bloomberg L.P. He has a net worth of $39.3 billion. Although, Bloomberg was the former New York City mayor and one of the richest politicians of America, now he keeps busy in restoring the media details and financial data of the company that bears his name. He returned as the CEO of Bloomberg News in early 2015 and since then he has shaken up the media house, by getting backing to basics, focusing on the major business news, and replacing the company’s top editor.
