Jennifer has posted that Microsoft have just sent out invitations to selected advertisers for adCenter – their contextual advertising program’s pilot program in the coming months.
She notes that the invitation indicates that ads will be primarily places upon MSN sites but that in using that word there is a chance that they might make it available for other publishers to run the ads (similar to AdSense and YPN).
This is one of the few indications to publishers that there is a chance of Microsoft heading in this direction sooner than later.
