Two days before,Microsoft’s upcoming Windows Phone 7 ads featuring HTC Mondrian with AT&T leaked around the Internet. The video was first uploaded by a company which made music for that ad in Vimeo. WMPoweruser.com first broke the story to Internet. From there on the videos spread like wildfire. Top technology blog sites like Engadget, TechCrunch, Cnet, Neowin, etc wrote on it. The videos had about 200,000 views each and generally had positive reviews. Now YouTube has removed those videos claiming copyrights issue from Microsoft Corporation. So this move obviously confirms that ads were real. People who haven’t seen the ads still can view it in hundreds of YouTube account and some sites like Engadget that hosts the ads on their own server.
