In the 90s there were ton of mom and pop ISPs. But in the 90s they piggy backed off of telephone lines (dial up) so they didn't have to have an infrastructure aside from running a high speed connection to their office and having a bank of modems connected to phone lines. I remember there was even a company that let you "start your own ISP" with just a 10 minute sign up form. You used their high speed connection and their modem bank and they took 3/4 the profit.
