YouTube seems to be a very special component within Google's universe. First of all, the company is apparently still working very independently from the rest of Google. Of course also YouTube is deeply integrated (Google+), but their upcoming music streaming service also clearly shows how free and unbound they’re still allowed to operate. This ambiguous relationship might also be seen best at the example of YouTube’s UI design. After receiving a great redesign in late 2012 - which aligned the service to Google’s back-then new clean style - the company had to face much criticism. And also YouTube’s Android app seems partly rather unsure about what it wants to be: of course the last great update in August 2013 brought in Google’s popular card scheme. But still without a colored Action Bar and still with a half transparent Navigation Drawer, the service is far less a reference app for Android design than most other Google apps. This is even more surprising considering that YouTube once was a reference app on the original iPhone.

And after all, YouTube was also one of the few Google services not even mentioned at this years I/O in the context of the new Material Design Language. And this although the very same service might actually could have been the origin of Material Design. It was most likely unintentionally, but the way you can minimize videos in YouTube’s mobile apps since the latest update clearly follows the main aspects of Material Design: motion and meaningful transitions. It might not yet be as polished, but similar to Material Design, the video is placed fixed, clearly above the other content when minimized, and when expanding it, it animates smoothly showing where the new content comes from, thus making the user understand the whole interface. So this concept imagines a redesign to the YouTube Android app explicitly following the Material Design guidelines. I guess the mock-ups and pictures do mostly explain themselves. It’s very interesting to imagine any app being rethought with Material Design, but YouTube - which is part of Google - might actually never feature it as deeply implemented as imagined in this concept.
