I'm going to comment instead of mod, since this topic is so dear to my heart. Let me wholeheartedly agree and go one step further than bashing targeted ads.
I'm against ads, period. Advertising has gone beyond informing me of a product to the point where advertisements, especially in TV and Radio, are manufactured specifically for the purpose of manipulating me into desiring the product being advertised. It is no longer, "Hey, buy this product if you're in the market". It is now, "Hey, watch as we manipulate you with images and sounds that play on your politics or emotions so that we can manufacture a desire for you to buy our product that you do not need."
Not only is this manipulation occurring, but many times it is occurring so blatantly and unabashedly that I become offended that the ad is being shown. Think: Chevy's ads juxtaposing classic Americana and John Mellencamp to sell their trucks (link). That I, as a watcher/listener of that show/channel/medium, am considered to be so stupid that I will bite on their emotional/subliminal advertising garbage, is so enraging to me that I will completely disassociate myself from the show/channel/medium in order to get away from advertising.
So I have abandoned commercial radio and television, and, frankly, I don't miss it. Advertising has gone from annoyance to something that I consider to be unethical and a serious contributor to our problems as a consumer society.
