Bloomberg L.P.

Bloomberg L.P. is a privately-held company primarily owned by three-term New York City Mayor Michael Bloomberg. Bloomberg L.P. is a financial information giant, selling primarily to corporate and other institutional clients via its Bloomberg Terminals, which cost nearly $20,000/year each. Bloomberg L.P. has also built a consumer-oriented business news operation, and has put all news operations underneath one umbrella called the Bloomberg Media Group. Bloomberg Media Group also houses BusinessWeek magazine, now called Bloomberg BusinessWeek, which Bloomberg L.P. acquired from McGraw-Hill in late 2009. Bloomberg Media Group also includes the monthly Bloomberg Markets magazine, Bloomberg Television and Bloomberg Radio, Bloomberg Government, and Bloomberg.com. As of 2011, more than 85% of Bloomberg L.P.'s revenue comes from its Bloomberg terminal. In 2005, Bloomberg introduced Bloomberg Law, which integrates legal content, company and client information, and proprietary news. In December of 2009, Bloomberg acquired New Energy Finance and formed Bloomberg New Energy Finance, a media division dedicated to covering renewable energy news. Bloomberg was founded in 1981 by Michael Bloomberg, Thomas Secanda, and Charles Zegar with headquarters in New York, NY.
