Mike Bloomberg

Mike Bloomberg is the founder and owner of Bloomberg LP, the financial data, software and media company he built from scratch after being dismissed from Salomon Brothers in 1981. Bloomberg LP's media arm — encompassing Bloomberg News, Bloomberg Television, Bloomberg Radio, Bloomberg Businessweek and Bloomberg.com — makes Bloomberg one of the most significant figures in global business journalism and media, with advertising and subscriptions underpinning a multi-billion-dollar enterprise. The Bloomberg Terminal, the company's flagship product, is used by roughly 325,000 financial professionals worldwide and generates the bulk of the company's estimated $10–12 billion in annual revenue. Beyond building Bloomberg LP, Mike Bloomberg served three terms as Mayor of New York City from 2002 to 2013, during which he was one of the highest-profile elected officials in the United States. He ran an unsuccessful campaign for the Democratic presidential nomination in 2020, during which his campaign became notable for its unprecedented digital and out-of-home advertising spend, reportedly exceeding $1 billion in a matter of months — one of the largest political advertising outlays in history. Bloomberg is also a major philanthropist through Bloomberg Philanthropies, which funds initiatives in public health, the environment, education and the arts globally. He has consistently ranked among the world's wealthiest individuals, with a net worth estimated in excess of $80 billion.
