Personalized advertising: you using a new product and visually enjoying it. Blows my mind people do not see this application.
I don't see that application because uBlock Origin filters it out for me.
You do but do not realize it. Very few realize how Netflix uses demographic product placements in their media, which I wager you've had and never knew.
It was a joke: as though the browser plugin were filtering out not only the ads, but my brain's ability to even imagine advertising.
I do sometimes notice product placement in shows and movies, and it annoys me - though the substitution of fake brands[1] also tends to break the spell, so it's hard to be as dogmatic about the practice as my general aversion to advertising would otherwise suggest. It is not a serious problem in practice, because I don't spend much time watching the kinds of shows where product placement would be relevant.
