Google has redesigned the Play Store and is pushing the new version to Android devices this week. The refreshed content store is significantly altered and makes locating apps, games, movies, TV, and music easier on the eyes thanks to new tabs.
For example, the landing page has clear and obvious sections for Apps & Games, and Entertainment. These tabs are further broken down into sub tabs with app/game categories and so on. The Play Store also now makes it easier to see which apps are compatible with Android Wear thanks to an icon that appears in the app description.
The updated Play Store is being pushed out slowly, so it may take a while to reach all devices.
