The percentage of broadband users in North america is closer to 50%.. the 10% figure is WAY too low for over here...
Heck, my ISP just doubled my bandwidth for free. My downloads typically go at 310kB/s now and there are no limits to the amount I can transfer. For the reasonable price of $45 Canadian dollars per month (+tax).
That's nice. In particular this ~50% number for broadband users.
According to Bitkom
in Germany currently ~50% of the ~80 million people have got Internet access. In about 2 years this will increase to > 60%.
However "just" ~5% have (A)DSL (kind of broadcast), which currently means in absolute numbers ~4 million people. Until 2006 the DSL user number will double to 8 million, according to Bitkom estimates. (Typically DSL users have got flat rates with no volume limit and download rates from 96 to xyz KB/s.)
So... in relative numbers this is not too bright, just 10% broadband users here in the near future. But in absolute numbers it's still a good market: ~8 million broadband users, out of ~50 million Internet users for your local distribution. :-)
