One doesn't have to necessarily have one of the newer Internet-enabled TVs to be using the Internet with their TV. One of the satellite providers in the US, if not both, is using the Internet to serve 'on-demand' programming, you get a device that works between your wireless or wired network and the TV, it then downloads the program to your DVR, and you're ready to watch the program.
That is an early version of it.
But the thing here is that a lot of cable systems out there do not have the capacity, or the desire, to feature some channels, and so this is the way to get specific programming to those that want it without having to provide the channel space for the programming. I've heard that is how a lot of people in some situations get BYUTV, or even other Church programming available via the website. All they have to do is fire up the Internet on their set, and they're ready to go. One of the reasons is they live in an apartment where the cable service is provided as part of the rent, and it doesn't carry BYUTV, or any other given desired channel for that matter.
It's true though that a lot of people may not want it now, that's OK as it is a new technology. But it is developing rapidly and at the very least preparations need to be made to utilize it in the not too distant future. The prices of sets may be a little higher now, but that will come down. Once it hits the right price point, and hits a critical mass in audience, that will be what makes it commonplace, and by then the programming will be in place rather than some of the stuff that is out there right now that is not well-done or otherwise not that good, and we'll see a lot of useful things come via the Internet on our TVs.
