David Carson on the challenges to online video and Web TV: "The Internet is a noisy feedback machine where billions of people can provide input. This is the medium’s inherent strength. People participate, while with television, people observe. This is not the same argument as the old “Lean forward, versus Lean back experiences”. The differences between the two are far greater than simple body positioning. One provides a way to feedback, while the other does not. So what does this have to do with online video? Everything! People can share, embed, create, and sculpt their own video experiences with extreme ease. They become part of the experience, as opposed to being observers of it. Online video companies try to facilitate and encourage this kind use. The “show” is not the experience, the user’s activity is – not unlike the way we think of the difference between TV and video games. You don’t watch video games - you play them."
