So, what stakes in the ground do we find regarding a definition of broadband in the UK? The following item from "the archive" provides an interesting Janus glance back, to the 1994 UK Government's "a capacity of at least x/a typical bandwidth of y" definition of broadband/narrowband:
DEPARTMENT OF TRADE AND INDUSTRY | Creating the Superhighways of the Future:Developing Broadband Communications in the UK | Presented to Parliament by the President of the Board of Trade by Command of Her Majesty | November 1994 | LONDON: HMSO œ6.75 Cm 2734

This document is also worth noting as an "archive piece":
a) The document's Annex states that it is the first Command Paper to be made available on the internet:
AVAILABILITY OF THIS COMMAND PAPER VIA THE
For the first time, the Government has made arrangements for
this Command Paper to be available electronically via the
Internet. The Internet is the world's largest network of
computers. It was established by the US Department of Defense in
1969, and it developed as a flexible network for academic users.
It now has millions of users. It provides an electronic mail and
information service, as well as a means of very wide ranging
access to databases and to information files.
This use of Internet is an excellent example of the innovative
approach to the dissemination of information which the Government
is seeking to promote, and also of the lead which the Government
as an information provider is able to take. HMSO, a Government
agency, has made the necessary arrangements. This document can be
