It looks like Wednesday is the day that Yahoo will launch its Publishing Network if this article at CNET is right.
‘Yahoo is planning to launch on Wednesday an ad network for small Web publishers intended to strengthen its hand against rival Google, a source familiar with the plan told CNET News.com.’
Looks like we (and numerous other sites) were right.
Update – looks like it’s official now with the New York Times featuring an article about YPN. Initially it will be just 2000 sites that beta test the network with this being opened up at the end of the year to others. Looks like those of us not in the beta have another 5 months of Adsense and need not get so excited about YPN after all. No prizes for where the 2000 blogs will be from I’ll bet.
