st there was the telephone, created in 1876 by Alexander Graham Bell. This now widespread commodity was revolutionary and eventually caused the telegraph system to become obsolete. The innate progression from there is a network of telephones, making communication ever easier and a lot more streamlined. Thus the start of the switchboard system.
The pioneer switchboard systems were ungainly, ugly looking contraptions. They were comprised of cables for each telephone and also a board of plugs which plugged into other telephone lines.

The switchboard systems for small towns and cities were automatic first. Those who wished to speak to people in other towns and cities had to request to get connected by the operator.
