BlackRock was founded in 1988 by former mortgage-bond trader Laurence Fink as the Financial Management Group within the private equity firm Blackstone Group. The company changed its name to BlackRock in 1992. 
The company merged with PNC Financial Services Group in 1995. In 2000, BlackRock began offering risk management and trade processing tools to external clients under the BlackRock Solutions brand. The tools were designed to provide portfolio transparency and increased efficiency. As of March 31, 2007, BlackRock Solutions provided services for over $4.5 trillion in securities and derivatives across 94 clients, many of whom are some of the largest financial institutions in the world.
In June 2009, the company agreed to acquire Barclays Global Investors, including exchange-traded funds platform iShares, from parent company Barclays Plc for $13.5 billion. The companies combined to create an asset management firm operating under the name BlackRock Global Investors with combined assets under management of over $2.7 trillion, according to BlackRock. Barclays retained a 19.9 percent stake in the combined company.
In April of 2012, Blackrock announced it would launch a trading platform in 2012 that would let the world's largest money manager and its peers bypass Wall Street and trade bonds directly with one another.
