While the unofficial WP7 campaign began as soon as the phone OS was announced, Microsoft has started to push, at least one advertisement, to YouTube. The video (posted below) shows a WP7 phone appearing out of a desert in a mirage like fashion. Although the advert will never be aired on TV, it's the starting point for product placement and advertisements of Windows Phone 7.
Microsoft states in the video that the “Revolution is coming” and gives a very quick glimpse of the interface. The video at the end directs uses to navigate to windowsphone7.com. This video could also be a glimpse into the marketing campaign that will most likely bombard consumers to help raise brand awareness for Microsoft.
