## Early precursors to the commercial internet
|
||
|
|
|
||
|
|
Prior to the commercial internet and the advent of the web, there were services
|
||
|
|
in the 1980s which allowed home computers to connect to limited public networks.
|
||
|
|
Example services: checking one's bank balance, paying bills, transferring money,
|
||
|
|
booking holidays.
|
||
|
|
|
||
|
|
(Presumably, the services would be hosted on a providers'
|
||
|
|
[mainframe](Mainframe_computers.md) or mini-computer, which the consumer would
|
||
|
|
access through something like time-sharing?)
|
||
|
|
|
||
|
|
|
||
|
|
|
||
|
|
The mechanism of connection was via a modem. A device that connected to your
|
||
|
|
phone's cradle. Digital signals from your home computer would be converted into
|
||
|
|
sound signals ("tones") that would travel through the phone transmitter to a
|
||
|
|
receiver at the service provider which you would "dial-up" beforehand.
|
||
|
|
|
||
|
|
In the US the main provider was Micronet in the 1970s, which became Compuserve
|
||
|
|
in the 1980s and eventually AOL in the 1990s. In the UK there was Prestel
|
||
|
|
provided by BT, first introduced in 1971.
|
||
|
|
|
||
|
|
These services had an expensive subscription model and consequently uptake was
|
||
|
|
limited.
|
||
|
|
|
||
|
|
In addition there were bulletin board systems (BBS), typically administrated by
|
||
|
|
hobbyists. Their personal computers acted as servers that other users would
|
||
|
|
dial-up to access. They permitted the sharing of news and messages and later
|
||
|
|
chat-rooms for realtime communication. Some of the biggest BBSs later became the
|
||
|
|
first ISPs.
