How did Bulletin Board Systems in the late 80s and early 90s work?
In: 70
People would put BBS software on their computer and advertise their phone number at computer stores and other bulletin board systems. Most used a dedicated line or even multiple lines. Software was mostly open source / freeware.
FIDO software was a popular choice and had a feature where FIDO systems would phone each other at night (to minimize long distance charges) and exchange DMs, message threads and files.
This was not unlike Social Media today, except it might take a few days for your messages, posts or file requests to propagate around the world.
