Why do we all love digital advertising? Id venture one of the main reasons is that it performs. With more people coming online and the web becoming more and more an intrinsic part of our lives, the opportunities for marketers to harness the power of technology and reach consumers across properties like MSN, Hotmail, Windows Live Messenger and Bing, are becoming more and more relevant..and valuable. Much of the onus is put on the platform, the data, and the accountability.
