Microsoft Ad center is the Microsoft inventor to grab ad revenue market share. Until the beginning of 2006, all of the ads displayed on the MSN search engine were supplied by Overture.
In November 2006 Microsoft Acquired DeepMetrix(a company situated in Gatineau, Canada) that created web-analytics software. Microsoft has built new product AdCenter Analytics based on the acquired technology.
In October, 2007 the Beta version of Microsoft Project Gatineau was released to a limited number of participants. But still Microsoft Adcenter is not available for publishers. But you can find publisher link at :
