It is my understanding that most ad companies are doing some sort of interest based data collection whenever they show an ad on your site. We see cookies from every provider dropped on our clients.

Some are more open about it (Google), others I "think" have been doing it for years.

We as consumers just have not been aware of it. Ever notice the creepy ads in Facebook? ;-)
