Apple TV and the economics of television

Steve Rubel on Apple TV: "Over time, niche content will change the economics of television. Millions of Americans will add one or more Internet-connected set-top boxes to their living rooms. Once they do, look out. As they discover there is niche HD video content that matches their precise interests, the existing TV networks will see their viewers erode even more. Further, brand marketers will see they don't need media to reach people in their living rooms. They too will produce their own content that will be distributed over the Internet for consumption on TVs."

For example: I'd love to watch a weekly 10 minute tour of the Prairie Garden Trust by Dr. Henry Domke. Just Henry walking and talking, sharing his love and fascination with the flora and fauna. Okay on a video iPod...great on Apple TV.
