As we look back over the history of communications for more than 100 years, what you tend to see is that models don't disappear. They diminish and they find a position within the overall system. There were concerns at one time that radio would disappear. Certainly, the role of television changes, just as the role of radio has changed and relatively stabilized. Again, it becomes difficult to say what the future will hold too far out, but we can certainly see a definite decline right now, with no obvious plateau in the future.
