Ask HN: What are the other premier ad networks beside The DECK, etc?

I am researching a bit about the so-called "Premium" Advertising Networks; so far I managed only to find these. Oddly, my Google results returned mostly USA-based ads network. - decknetwork.net - fusionads.net - buysellads.com - carbonads.net - federatedmedia.net Do you know what any other premium ads network out there? I'm sure there's somewhat similar network supporting the Spanish/German/Russian sites as well. Any help is appreciated.
