Companies like Walmart, Target, Tiger Direct, Hallmark, and many others use Linkshare to hire affiliates to promote their links and offer commissions on each sale.
Clickbank (by the way, want to host multiple clickbank ads at once or have your own clickbank storefront? You can do so with CBproads, as they give you all kinds of widgets and resources you can use to promote clickbank products).
Ad Click Media, Kontera and Adhitz - these sites are similar to Google adsense, where you can host ads on your website/blog and earn money whenever people click on them
Other services and resources:

Easy Downlines and Traffic Exchange Profits - these are 2 free to join marketing systems that you can use to build your downlines at traffic exchanges, safelists as well as participating MLM companies, such as Global Domains International (a web hosting company) as well as Traffic Wave (btw, Traffic Wave is pretty useful for traffic exchanges as you can create lead capture pages and use Traffic Wave to generate the leads and send follow up messages to them).
