I have thought about this idea of broadcasting my plans for a while now. Everybody is saying that google's adsense is the biggest breakthrough in advertising in years. Think about the potential of being able to register that you are thinking about buying a car and then only seeing car commercials. I'm not talking about just adsense on the right margin of webpages but even in your tv shows and radio programs on the way into work. Or being able to say "Hey I'm overweight I want to ban all ads for unhealthy food and or alcohol across the board!". Currently I'm thinking of remodeling my kitchen; I would love to only see ads for local companies that can do this. I mean sometimes I spend my free time researching which computer I want to buy. I can't imagine that companies wouldn't want to take advantage of this and put in custom ads for me. I realize that this would represent a shift of power from the ad agencies to the consumer but so be it. I think the companies buying ads would benefit from more targeted advertisements.
