I have been with msn adcenter from the beginning and looking forward for a publisher network, but I haven't heard any news, so it seems to be in the distant future
Its going to be called ContentAds (their publisher program). I believe its way off. Probably 6 months at least after whenever YPN goes international.
Damn, I wish they released it at the same time as AdCenter. Is it going to be open to almost everyone like google or is it going to be only for websites with really good statistics?
Does MSN have a large network of advertisers? that will affect the inventory they have. I know google has large inventory, hence ads are highly targeted and very effective.. the smaller ones have small inventory and the PPC rates are terrible like 0.03 per click.
