A 'trading' ad network?

I've read about an ad network that lets people advertise on your site for a fixed amount of pageviews, and then you get to use that amount of pageviews on any other sites in the network. I'm not able to find any of these via Google though, so I guess I'm not using the right term.

Can you guys set me in the right direction and, if you've used an ad network like this before, share your experience with it?

Thanks

 

They are called exchange networks and usually are niche specific.

What niche are you after?

 

Gaming niche is what I'm looking for, but I remember a very large all-encompassing one too. In any case, leads to a site for gaming niches or the latter would be great.

Thanks Paullie
