@HarriLuuppala @JosueMVivas Not worth arguing about.
@HarriLuuppala @JosueMVivas Wikipedia says: "With this help the Strowger Automatic Telephone Exchange Company was formed and it installed and opened the first commercial exchange in (his then home town of) La Porte, Indiana, on November 3, 1892, with about 75 subscribers and capacity for 99. "
@miguelpdl @workergnome Yeah, that "international link to London" went through our local IMP in NORWAY which was connected via satellite at Tanum in Sweden to SDAC in Virginia. Homework: Why are there seismic monitoring stations in Norway which has no earthquakes ?
