Because the U.S. has been so slow to introduce interactive television, by definition the Internet will play a very important role in the rollout of iTV in the U.S. While, of course, it makes sense that the Internet can be the feedback channel for an interactive television systtem, I suspect that the Internet will become an interactive television medium in its own right. So, fellow new media travelors, I suggest watching developments with IPTV (another reason, by the way, that interactive television in the U.S. is not a possibility or even a probability, but a certainty).
Here is a site that's a good place to check out now and then to see what's on TV on the Internet, wwitv.com.
