The 'Scientist' in the first commercial video demonstrates how movie streaming works in Google Play using a bannana, yes really. It might sound odd, but the commercial is very straightforward and easy to understand.
In the second video, album sharing is explained with Google Play using juice. I know this all sounds weird, but they did a very good job of explaining things in a humorous yet easy to understand way. It's likely this is just the first of many similar videos to come, and I wouldn't be surprised if these start hitting the TV networks sooner or latter.
