I didn’t yet heard about AdvertisingSpace, thank for the info.
I tried infolinks but it slow downed the website. Bidvertiser was good but the problem was that it didn’t count some clicks.

What will be the best Publisher program for my SMS website
try infolinks
I think Infolinks & kontera type ads is much better
don’t try infolinks, they are real suckers
I think you can remove infolinks – it’s not good. You can add AdBrite and Technorati media to the list.
Great list thanks I recently setup my blog and didn’t think of adding infolinks or Chitika. Thanks for that tip.

AdMedia.com pay per click (ppc) program for publishers is no alternative to Google AdSense. It is not even an alternative to AdBrite and most publishers know that AdBrite’s payouts are very low. AdMedia.com is the king of low payouts.
AdMedia.com mostly pays 0.1 cent per click. AdMedia.com ad system seeks to pay publishers the lowest revenue possible. Most clicks are not even paid the penny because they are labeled Fraud clicks or are dropped.
Publishers, stay away from AdMedia.com. Don’t let them fool you with their contextual ads advertisement.
nice list…..
Infolinks and Kontera are really waste of time and visitors. Never use them.
believe me these look like alternatives but really there is no competetion to adsense.
