Me too ...Phone landlines, after the A/D conversion, were a 64kbit channel, 8bits x 8000/s, usually one bit was stolen by the network.
At the then popular $0.10/minute long distance rate after the Bell System was broken up by the Telecommunications Act of 1984:
One gigabyte of data would take around 39.68 hours (if no problems)...
And at 10c/minute cost $238.
The poor old long distance phone companies sure had their business model broken with the expansion of the data networks.
I was there.
This structure was so convoluted that at one point from Miami it cost more to call Fort Lauderdale (10~15 miles) than San Francisco !!!
I am pleased it is dead...
