Microsoft is trying to revive its Microsoft Network Website by redesigning it specifically for the upcoming Windows 8 operating system. Microsoft will make MSN the default home screen of Windows 8 computers and modernize the look of the search engine Bing, MSN Money and Bing News, which is being optimized for Microsoft's Surface tablets. "We are using Windows 8 platforms to re-imagine digital surface areas. Some of those experiences are naturally ad-funded. That is why advertising is an important business for us," Microsoft president of Web services Qi Lu says at IAB MIXX.
