The BBC and WGBH Boston co-produced a documentary series, The Machine that Changed the World, in 1992. This excerpt follows the meteoric rise of Apple, begining with Steve Jobs and Steve Wozniak selling circuit boards at a 1976 convention for computer hobbyists.  At one point, Wozniak reflects on Jobs:

I was not designing a computer with any idea we would ever start a company, ever have a product, ever be successful. It was just to go down to the club and show off, and to own and use. Steve saw the interest, and he started coming up with ideas right away: how this thing could be turned into product, how it could be marketed.

The series is full of great interviews and archival material, and can be watched for free at the Internet Archive. For more video of Jobs, check out the Atlantic Wire's The Best of Steve Jobs's On-Camera Performances as CEO.
