The Internet has been the most fundamental change during my lifetime and for hundreds of years.

I think we've been an agent for change, everywhere, and I think change frightens people. They're going nicely in what seems like a settled industry, and someone comes in and says "I can do this better. It doesn't matter how nice that other one is." That's one of the distinguishing points of our acquisitions.

Most newspaper companies still have their heads in the sand, but other media companies are aggressive.

Becoming carbon neutral is only the beginning. The climate problem will not be solved by one company reducing its emissions to zero, and it won't be solved by one government acting alone. The climate problem will not be solved without mass participation by the general public in countries around the globe.
