The production of Olli energisers began in Sörnäinen (Helsinki) in 1938. In 1947, the people were informed about a new kind of energiser, an electric-powered “robot” that freed the shepherd boys patrolling the pastures for other tasks, by an actual promotional film!

Even though the energisers and fencing accessories have since evolved and diversified extensively, the basic principles of electric fence operation presented in the film are just as valid today.
