Russian friends tell me that in the cold-war era Soviet Union, the official state radio was brought into every building by means of the AC power distribution system. All comrades were required by law to always have it ON; in fact, there was no OFF button!
Yep... one enormous (and un-jammable) "intercom" piped into every workplace, restaurant, shop, and living room.
Hush up... Big Brother is talking!
Funny thing is... typical Americans nearly do the same thing with our constantly ON television, the difference being it is Madison Avenue creating in us the "perfect consumer" :roll:
At least, though, my OFF button works. :wink:
