I really am out of my depth on contextual stuff but is there any networks that actually run contextual campaigns? For the type of stuff i am doing at the moment it would be pointless having generic campaigns but keyword driven banner ads or at least contextual would probably do the trick nicely.

I had a small go at google banner ads but there wasnt even any affiliates in their network that put them on their site so it was a waist of time.

I have some really nice creatives but no home to put them :-(

any ideas?
