I believe that Silicon Valley is truly a place of excellence and the impact of this tiny community on the world is completely disproportionate to its size. We are the undisputed leaders of technological change. But with our abundance of talent and resources, we also have the opportunity to be the pioneers of social change and, ultimately, this may be our greatest contribution.

Participant (Productions) is the only production company in town that has a double bottom line: social good plus financial returns. It's too early to tell how our returns are going to look - though all signs are promising - but social good is what we're really after.

Philanthropy is all about making a positive difference in the world by devoting your resources and your time to causes you believe in. In my case, I like to support causes where "a lot of good comes from a little bit of good," or, in other words, where the positive social returns vastly exceed the amount of time and money invested.

The pace at eBay was frantic and urgent. We knew that if we didn't move fast, somebody would come into the market and quash us. Participant doesn't make a lot of sense from a financial investment perspective, so it's unlikely that other people will be approaching the business in the same way. So you see less urgency; you see a thoroughness and willingness to spend extra time to get things right. Which I think is really important.

The goal here is to build a brand around social relevance in media (with his Participant Productions company).

I learned Hollywood is a small community, and you really have to be a part of the community to get anything done. Unlike traditional industries, where you can do things from afar with phone calls and e-mail, this town is really about being social. Because that's how trust gets built.
