I just found this video while surfing around youtube. I'd read a few times online about BT were going to go to full fibre decades ago. So watching this presentation was very interesting.
1985: The case for full fibre to the home - Peter Cochrane, CTO BT

Filmed in 2006 at the 21C Global Summit, then BT CTO Peter Cochrane talks about the 1980's proposal to use fibre optic all the way to the home and why, in the end it took 30 years to be approved. For anyone involved in telecommunications or engineering this is an incredible presentation.
