Reporters of the Wall Street Journal have produced a three-part video series on the crisis on the Street, looking at What happened, Why it happened and What happens next.
This is an excellent overview of the financial malaise.
Chapter one: What happened
How the housing bubble inflated and burst, and why easy money led to the collapse of Wall Street's biggest financial institutions.
Chapter 2: Why it happened

Chapter 3: What happens next
This final chapter tells the story of the $700 billion bailout and looks at what's ahead for the global economy.
