Why Goldman Sachs, a Wall Street powerhouse, is going after the masses

How Goldman Sachs became the most powerful investment bank on Wall Street

The investment bank was founded by Marcus Goldman 150 years ago, and has been a major player in banking for over a century.

Marcus' son, Henry, revolutionized company valuations, leading to the IPO of Sears Roebuck in 1906.

The company was the gold standard in investment banking for decades helping bring Ford Motor and Disney public.

And partners including Henry Paulson and Jon Corzine got fantastically rich when the company went public in 1999.

But the firm's reputation took a beating during the financial crisis, eventually leading to one of the most interesting pivots in Wall Street history. Now, the company is going after the regular consumer with a new digital banking product, Marcus, and a partnership with Apple.

Watch the video above for an in-depth look at the history of Goldman Sachs and what's next for the storied firm.
