Online Advertising Technology 4

So there we all were, happily surfing away, not a care in the world. What most of us didn't realize was that enough free cookies were being distributed to each of us to turn the otherwise docile Keebler elves into tree-dwelling Mafioso erroneously plotting a turf war.

These cookies, of course, are the ones that websites place on your computer when you visit – little packets of information that record your visit, and sometimes, your activity there. Certainly, there's a legitimate reason for this. When you return to a website, it can help if it remembers your last visit and you can pick up where you left off. Assume, for example, that you were making multiple purchases from an e-commerce site and had a bunch of stuff in your shopping cart but were forced to abandon the site before completion. It's nice to go back and pick up where you left off without having to do it all over again.

Digital advertisers, however, saw another opportuníty for targeted online advertising. They invented advertising technology that would scour through the cookies on your personal machine, figure out what you liked and disliked by looking at the types of sites you went to, and then feed up highly targeted online advertising based upon your browsing history.

These companies included aQuantive, DoubleClick, ValueClick, and others. Of the companies I mentioned, only ValueClick is still independent. Google snapped up DoubleClick, while Microsoft snapped up aQuantive. Clearly, these companies believe in the future of Internet advertising technology and also believe in the long-term legality of this technology.
