News comes out that MSN Adcenter will be arriving in June to the USA in full force.
One interesting note in the article is:
The launch is also a major step toward Microsoft’s broader adCenter ambitions, which executives say will eventually be a system for offering companies ways to buy online advertising space on multiple platforms, ranging from its blogging sites to its newly launched Office Live system for offering business software and services online.
It will be interesting to see how much traffic the Office Live system will create for advertising. And that could be very valuable inventory. The plot thickens.
