The thing is, it’s quite easy for a marketing department to measure their success. They release an annoying unskippable YouTube and and change nothing else in their marketing and their profits go up by 1% or whatever. As much as I basically do no shopping where the day to day advertising I see can influence it, that’s a pretty abnormal lifestyle pattern. Plus I’m still susceptible to choosing specific items inside a shop, and I definitely susceptible when I’m looking for specific products and come across secret ads disguised as advice.
