We'd be in control of the newscast, not some guy making assumptions about what we want to know. Of course that's not going to happen soon. The computing power just isn't there. They're all trying to feed our craving for true interactivity, but they're doing it with passive interactive content. It sucks big time.
People flock to the site initially, discover how bad it is, and leave disappointed.
Let me clue some of these people in. That's where your content is targeted specifically at a user. Going back to tennis, the Internet could have given me the same live Wimbledon feed, but given me a choice of announcers. I could have selected a broadcast for beginners, where they show things in slow motion and explain in great detail exactly what's going on. Once I understood the game, I could tune in to a more advanced broadcast, and later, a still more advanced one.
