I didn't say that it had been going on for
five years..just that would seem to be a likely
horizon of investigation. Nor that it was a constant
concerted program. Asa far as the number of people
"in the know", I think that does not need to be as
large a group as you think. Could be a small group
of rogue techies,acting on the larger sentiment
of the Communist News Network culture, with access
to the main control facilities...remember that most
people in the control room need not know that
the signal has been altered, for it to be looked
at by them, and aired, messages inserted, if
they aren't seeing it being done.
Could be as simple as a trojan program, and a
single person operationg a remote key switch.
...till something goes wrong.
