national radio (esp. an NHK radio station)
Kokumin radio (German: Volksempfänger) is the general term for a series of radio receivers that were mass-produced and sold at low prices as a means of propaganda against the general public in Nazi Germany. By 1939, 70% of all households owned a radio receiver. This was the highest penetration rate in the world at that time.
Some people may be concerned about this now because of the negative things that have happened as a result of efficiency, but technology is neutral, and it can be good or bad depending on how you use it. As technology makes human behavior more efficient, human behavior with bad intentions also becomes more efficient, and evil is done efficiently. The only way to combat this is for people with good intentions to become more efficient as well. Even if you try to bind them with ethics or law, people with bad intentions will ignore them. ---
