(Artificial) Intelligent Advertising

Today, while trying out the latest offering by Microsoft, MyPhone (for Windows mobile devices only) I came across several advertisements for Blackberry phones on Sprint network. That's when it occurred to me that online advertising, has to go extra mile in ensuring that there is some amount of Intelligence in the way, advertisements are put on various websites.

We come across several Ad programs like Google powered AdSense. To match a product which has such a name, I think it should be able to sensibly filter advertisements of a competitor on your own site.

Has anyone ever found a pair of Nike shoes in an Adidas show room???
