We have partnered with Microsoft and Yahoo! to meet advertiser demand and provide easier access to high quality online display inventory. This agreement should dramatically improve the process of buying and selling premium online inventory in Canada. Under terms of the deal, AOL will soon have the ability to offer premium non-reserved owned and operated display inventory from Microsoft and the Yahoo! Network Plus to our advertising customers.
Similarly, Microsoft and Yahoo! will also be able to offer AOL's owned and operated, and third party non-reserved inventory to their own advertising customers, and deliver commensurate value to their publisher partners, as well.
For more information, please read the AOL corporate blog post from when the deal was formally announced in the US.
