Seems to me, they're asking the wrong question. Decades ago when I was a much younger artist I studied the subliminal suggestion meme that was popular at the time. The practice was not to place subliminal ads into images, it was to place subliminal suggestions into images so that in alcohol related ads the word 'sex' would be vaguely drawn into ice cubes and distorted images of faces and bodies. Its unclear if any of this stuff was ever commissioned or if it was just boredom being played out by the ad designers. Hard to understand how the effect could even be measured.
