The problem is OB, that earlier in this thread you indicated that you think the longer term is something like 10 years.
In the UK, this simply will not happen, if only because the BBC's charter is renewed every 10 years, and the continued existence of the BBC until at least 2026 will perpetuate linear TV as a viable content delivery method.
There is no doubt that 10 years from now, all the linear broadcasters will have a sophisticated on-demand offering, however there is absolutely no chance whatsoever that an imminent end to linear broadcast will be on the cards.

Oh and by the way, if our Internet usage continues to increase at its current rate, not only will we saturate the current data infrastructure within 8 years, that infrastructure will require the UK's *entire* current electricity generating capacity to keep it lit, within about 20 years.
Both those timescales are worrying, because they challenge the usual pace of expansion in both cases.
There simply *will*not*be* a complete switch to on-demand TV for the foreseeable future, because if at any point in the foreseeable future we were to try to do it, we would find we had neither the network capacity nor the electricity generating capacity to sustain it.
