Rising quickly in the financial industry, he ran Salomon Brothers' information technology department and became a partner. In 1981, after a merger, he was fired, but anticipating a growing need for business information, he used his $10 million severance to start a financial data and communications company, Bloomberg L.P. The company grew rapidly into a huge multifaceted enterprise that provides real-time financial and business data, historical data and analysis, and electronic communications and produces television and radio programs. Bloomberg became a multibillionaire and a noted philanthropic donor. Long a Democrat, he ran in 2001 for New York mayor as a Republican, spending record-breaking amounts of his own money, and was elected to succeed Rudolph Giuliani . He was reelected in 2005. In 2007 he quit the Republican party, becoming an independent, but after mayoral term limits were ended he won (2009) a third and final term as a Republican. In 2014 he was appointed United Nations special envoy for cities and climate change.
