As internet gets fast enough for streaming video to work reliably, isn't normal and even Sky TV going to become obsolete? If you can just watch the TV station over a web connection then why keep all those aerials on our houses?
Wouldn't it be cheaper for TV companies to broadcast over the web than to have huge transmitters?
And that's not even thinking out being able to choose to watch any program at any time...
I've never heard any plan for this to happen - they talk about turning off normal TV in favour of digital and then HD, but never of switching to a web-based system that I have heard.
