History
Bloomberg L.P. was founded by Michael Bloomberg in 1981 with the help of Thomas Secunda, Duncan MacMillan, and Charles Zegar. Within 10 years of its founding, Bloomberg L.P. had made over 10,000 installations of the Bloomberg Professional service, a groundbreaking data, analytics and information-delivery service. In the same decade, Bloomberg opened offices around the world and launched Bloomberg News.
The next decade saw subscriptions skyrocketing to 150,000 while Bloomberg.com and Bloomberg Tradebook launched, allowing traders to trade stocks directly through the Bloomberg Professional service. This past decade saw more rapid growth, with technological innovations continuing to make Bloomberg the professional’s choice for data, analytics, news and more. Subscriptions doubled yet again to over 300,000 as new and better algorithms allowed finance professionals to stay ahead of the competition.
