"Google recently spent more than $3 billion to acquire DoubleClick, a banner-ad-serving company that derived its value from having profiles on visitors to the net’s most popular sites and letting companies target their ads to particular groups. Google will now combine DoubleClick’s targeting with info from its sprawling AdSense network … and will quickly be able to build up robust profiles on Google users, whether they have an account or not. But more intriguingly, Google also announced YouTube ads will become targeted by categorizing what you watch, say and do on YouTube — combined with the other info from its DoubleClick. … That’s Google slyly telling you where all this is heading. Google says its mission is to organize the world’s information and make it universally accessible and useful. Google often says that it believes ads are information. What it doesn’t say, but clearly believes, is that you are information to be indexed, made accessible and useful."
