Somebody talked me into writing an autobiography about six or seven years ago. And I said I'd try. We talked into a tape recorder, and after a couple of months, I said, To hell with it. I was so depressed. It was like saying, 'This is the end.' I was more interested in what the hell was coming the next day or the next week.

We have no intention of failing. The only question is how great a success we'll have.

There is so much media now with the Internet and people, and so easy and so cheap to start a newspaper or start a magazine, there's just millions of voices and people want to be heard.

We're not a manufacturer, or an airline, but we do use energy. Printing and publishing newspapers, producing films and television programs, operating 24-hour newsrooms. It all adds carbon to the atmosphere.

Advances in the technology of communications have proved an unambiguous threat to totalitarian regimes: Fax machines enable dissidents to bypass state-controlled print media; direct-dial telephone makes it difficult for a state to control interpersonal voice communication; and satellite broadcasting makes it possible for information-hungry residents of many closed societies to bypass state-controlled television channels.

Some of our businesses use more energy than others, but our strategy everywhere is the same... first, reduce our use of energy as much as possible. Then, switch to renewable sources of power where it makes economic sense... And, over time, as a last resort, offset the emissions we can't avoid.

Imagine if we succeed in inspiring our audiences to reduce their own impacts on climate change by just 1 percent. That would be like turning the state of California off for almost two months.
