I get it. This stuff is effective. Sometimes. And sometimes is enough in the amorphous world of advertising. To me, it is a bit creepy that the things I have browsed in idle moments pop up with amazing specificity and constant repetition. I'm half-tempted to just buy the damn products in the hope that other ads will appear. But, somehow, I doubt that would happen and there's no sense in rewarding these advertisers for annoying me.
Then, a thought struck me. Is it possible to buy advertising from Google that only targets me? Instead of seeing these annoying ads, can I pay Google just to show me my favorite pictures or funny quotes?
