Microsoft has re-announced its ContentAds program last Friday. The program is currently in private beta, as we have reported at the end of 2006, but we have covered it since the beginning of 2006 Microsoft's post seems like more of a clarification, based on the recent TechCrunch post, which called the launch new.
About 11 months ago, ContentAds was rolled out to US publishers but Microsoft acknowledges that it's in a "private pilot phase."
Many publishers, particularly as voiced at WebmasterWorld, are excited to try this program out. They don't, however, have access yet. You can see the login/signup page here.
I, too, can't wait to hear the first impressions of ContentAds.
Forum discussion continues at WebmasterWorld and DigitalPoint Forums.
