Cut and paste from the official fan website.
When The Archers first began, the aim behind the show was to spread information to farmers on how they could increase their productivity following the rationing and food shortages that were taking place at the time. It revolved around the lives of three farmers. There was Dan Archer who managed to be productive, yet he had very little money. There was Walter Gabriel who also had little money but was unable to practice efficient farming with what he had. Lastly, there was George Fairbrother who farmed with the aim of making a loss. In this way, he ended up paying little taxes, a scheme that many people used in those days.
