When Salomon was acquired by another firm, Bloomberg left the job and started Innovative Market Systems, a financial data-services company in 1982.

In 2002, the firm was renamed Bloomberg LP which became a global leader in financial data services. Bloomberg computer terminal, a comprehensive financial news and information source is the main source of revenue of the organisation.
