Google has unveiled a new behavioral targeting system that'll read your browsing history, then cater ads based on where you've been. While Google sells the concept as an user-oriented improvement that'll bring you "more interesting" and "useful" content, you may want to consider the privacy implications of having your surfing habits monitored and monetized.

If there's one site you visit, it should be the Network Advertising Initiative's Opt-Out Tool. NAI, a consumer awareness organization, has created a handy utility that lets you see more than two dozen ad networks that may be pulling your info (even though you've probably never heard of most of them). The page shows you which companies have cookies set on your computer, then offers you an option to turn them off.

· Google's ad system has its own opt-out page here.

· Yahoo's targeting program lets you say "no thanks" here ...
