Nicola's resources: 1 - Ad networks

• AdSense (of course)
• PayPerStats They started from Italy and are going to rule the world (!)
• LinkLift
• Adconion
• FeedM8 Feeds on your mobile (and ads in your feeds)
• OrangeFeed
• TextLinkAds The one I prefer. They provide you an interesting service, too: Link Calculator
• Kontera
  

• OpenAds it's not an ad network, but it provides an updated list of them.
