JenSense had a really nice find, I mean really nice find. She discovered based on reviewing a session she is speaking at, at the Mix06 conference. Go to the sessions and select "Jed Nahum" from the speaker drop down list, and click "search." Up comes this information;
Introducing adCenter – Microsoft’s Next Generation Advertising Platform
Speaker(s): David Jakubowski, Jed Nahum
Session Type(s): Breakout
adCenter is the next generation of online advertising that will allow you to conveniently plan, execute, and adjust your online advertising programs. Get the insider view of our current search advertising pilot in the U.S., our plans for ContentAds in 2006 and a preview of the innovations we're testing at the Microsoft adLabs.
Remember where I over heard Jed Nahum at SES, I wrote MSN Contextual Ad Program Coming Soon? Well based on this information, it looks like the MSN Contextual Ad program is named ContentAds and at least a limited beta will be released in 2006.
I really have no idea why the forums are not buzzing about this. I started a thread at Search Engine Roundtable Forums.
