This new world of personal media - the Web, the Internet and et cetera - not only delivers the world to your living rooms, but everywhere. And we get to answer back. And we're expected to answer back.

The arrival of television established a mass-media order that dominated the last 50 years. This is a personal media revolution. The distinction between the old order and the new order is very important. Television delivered the world to our living room. In the old media, all we could do was press our noses against the glass and watch.

If you look at the last 150 years, about every 30 years or so, a new scientific discipline emerges that starts spinning out technologies and capturing people's imaginations. Go back to 1900: That industry was chemistry. People had chemistry sets. In the 1930s, it was the rise of physics and physicists. They build on each other. Chemists laid the experimental understanding for the physicists to build their theories. It was three physicists who invented the transistor in 1947. That started the information revolution. Today, kids get computers.

I think it was Samuel Johnson who said, "There are two kinds of information in this world: that what you know and that what you know where to get." The tools help the latter, and that's what keeps us from going nuts. The sense of overload comes from the gap between that sudden jump in volume (of information) and the tools we have to make sense of it.

Every new thing upsets people. We all know someone that has a teenage kid who sits in the room and the television is on, their iPod is on, they have the computer on and at least three other electronic devices going while they're doing their homework. It drives the dad nuts, but he can't complain because the kid's a 4.1 (GPA) student.

People were touchingly naive at the dawn of the Internet revolution when they said the Internet will route around censorship the way it routes around damage. With any revolution, the establishment catches up and figures out how to screw it up. The answer is to keep technology advancing fast enough so that those who would try to control it can't. It's up to people to defend what they care about. We shouldn't be complacent that this stuff is going to be a force for good.

The most important thing that a company can do in the midst of this economic turmoil is to not lose sight of the long-term perspective. Don't confuse the short-term crises with the long-term trends. Amidst all of these short-term change are some fundamental structural transformations happening in the economy, and the best way to stay in business is to not allow the short-term distractions to cause you to ignore what is happening in the long term.
