What was invented was a very low rate (equivalent to local calls) for 
subscribers *anywhere* in the country to call these numbers provided to 
ISPs. Part of the low cost was enabled by the way the ISPs were required 
to invest in a fibre connection from the telco's exchange to their modem 
banks. If you were lucky both would be in the same building.

The main loser was BT, who lost all that long distance call revenue. 
Cable companies not so much, as their territory tended to be in large 
metropolitan areas which already had local POPs.
