Yeah, I was afraid the reference was a bit obscure. ISDN didn't
really catch on much in Europe either, except for Germany
and the countries in Scandinavia. I doubt many people still
use ISDN in Europe, though.
Take Sweden, for example, the government forced the providers
of fiber-based broadband to also build the infrastructure
outside the major cities. What this means is that most people
in Sweden can cheaply get 100Mbit broadband.
