I've had a few conversations on here about the corrosive impact of advertising and whenever I do I always see one comment that I sympathize with, but all find concerning.
"At this point when I see ads it makes me want the product less."
I think nearly everyone has felt this way from time to time, and yet the "adspace" keeps expanding to new frontiers and levels of obnoxiousness.
Advertisers know that their ads are effective. Even on people who have promised themselves they aren't.
