>>16909338it doesnt work.
the powers that be dabbled with this a bit in the 30s-60s, hiding secret messages on film between frames or inside animations. everything from "drink coca cola" to "the government is your god"
originally the numbers showed results, but then it was discovered that the guys running the test were flat out fudging the numbers. the test was run again without their interference and nobody bought more coke, patriotism didn't change, whatever.
so they went back to the good ol method of hammering the public over the head with the message until they agree.
we're dumb enough for it to work. why change things?
