24(1998) years ago we paying $1000 per MB to access a computer network at 2400 baud for EDI (electronic document interchange) to Sterling Commerce for swapping files with vendors. This was pricing and tech from 1990. The modem cost $~800 as it was a different format somehow. I thought this was all insane having an personal 128K ISDN line at home and Netscape was a 16MB download. This would be $16,000 download, the price of a new car!
What's crazy is that the EDI market is still cornered with VAN's charging absurd rates. It still shocks me everytime I get involved in a project and the EDI portion is like $100,000 a year in VAN charges and they don't blink an eye.
