What I'm saying is, Virgin could have started offering these recent speeds many many years ago, if they had BT would have been forced to react to stay in the game. Even now the take up of 50Mb is low.
As for innovation that's a bit of a cheap dig, BT have and still are very innovative. They invented Blown Fibre...... after all.
BT could have started moving towards a fibre based last mile a very long time ago.
It was privatised 27 years ago. It is now investing 2.5bn upgrading its last mile network. Divide 2.5bn by 27 and it's not a particularly big sum.
Where we agree, I think, is that the expansion of the VM network and the impending LTE/4G services are the reason for BT's FTTC programme.
Except that for all the reasons already covered in this thread, the former is slow to non-existent, and the latter is still some time away and will not provide very many people with "superfast broadband". At least, not at the same time.
The other and perhaps main reason for BT's sudden decision to actually invest in its last mile network is what I alluded to above - on the front page there's a news item suggesting that the number of fixed landlines is in decline.
