Microsoft's own advertising blog (yes, it exists) has revealed how its going to frame ads inside incoming Metro-themed apps. While announcing partnerships with six different ad design teams, Microsoft threw up an example, above, that ties together a Seattle Sounders FC app with a panel showing off a pair of Adidas' latest Predator cleats. The adis located at the far edge of the apparently scroll-able app and clicking / tapping on the side will launch into a dedicated page, with a back button visibly ready to swing you back. While it looks relatively unobtrusive at the moment, the background of the app will also be up for advertising grabs, able to integrate videos, text and other media. Let's hope it doesn't ruin those delicate Metro lines when Windows 8 finally arrives.
