When I was young there was a telephone number that people could call and for some reason the switching mechanism was bad at the phone company. As a result whenever you call that telephone number you would be connected to a whole bunch of other people who were using the same number to communicate through what we called “the pipeline.”
It was like an early form of Twitter. This all took place approximately 1962 or 63.
We called them 'party lines'. We had them in rural Texas because it was too expensive to run individual lines to homes, so they ran one line that had individual numbers for each home. (At least that's the way I understood it)
Folks were known to pick up the phone at random times just to listen in on other people's conversations. Maybe that's why people in small towns always knew everybody else's business! LOL!
Was it a party-line or something like it?
