I'll try to explain it in short:
You visit AboveTopSecret, and an advert loads on the page.
When the advert loads it has a refferal header of the page that you loaded, so the advertising company knows what content you were reading or looking
You then visit another website which uses the same advertising company to display adverts, a refferal header of this page is also sent to the advert
server, and they know which page you were looking at.
If you add cookies to be placed on the machine when a user views an advert, it's a unique id, and everytime you load an advert in your web browser
from that same advertising company, they can log and keep track of every page you visit which happens to contain one of their adverts by looking at
the refferal header alone.
Effectively the cookie is sent to their advert server each time an advert is loaded allowing them to generate a profile of websites that the user is
interested in. So after a bit of browsing, say you went to an astronomy forum, and a telescope store which contained the same advertising companies
adverts... they will start offering adverts related to telescopes and astronomy.
The same goes for if someone visit's several car manufacturers websites that happen to host adverts from the same advertising server, when you visit
a site about gardening you will most probably receive adverts about cars.
It's a dirty tactic.
