On the other hand, outside of Proctor&Gamble-esque juggernauts of all things cheap and disposable in the grocery store, there's tons of stuff that appeals to small groups; this is a lot of what the internet and globalization has provided.
For example, my total spending on video games in the last 5 years is between 0 and $100, so game publishers should probably save their ad spend (and not annoy me with noise). My TV is seldom out of the closet and plugged in, and I spend maybe $1-200/month on books. I'm pretty interested in buying a tennis stringing machine and more sheet music to play, but it's too much effort for me to seek those things out, so I don't. These are just a few of an infinite array of identifiers that could provide worthwhile targeted ads to me.
As another example, most charities have a group of people who would be happy to give them money if they knew about the organizations, while most of the population is indifferent or, in some cases, opposed to their work.
I don't like advertising much, either, and it doesn't reach me that often, but it's ridiculous to suggest that personalized ads have no value.
