Not exactely, I think what's here are called 'Ad Words' or something like that. Basically directed advertisement based on the words on the screen. If you'r reading a thread about laptops, then you'll usually see computer ads. Reading a thread about cars, then you'll see auto ads.

All of these ad scripts can be tricked to generate more 'clicks' and a bigger payout. Do a search for 'click fraud' and you'll come across some apps.
