Google says it's "evolving" the Android market into Google Play. It's a smart move--unifying multiple services (Google Music, Android Market, Google Books and Google Movie Rentals) into a single shopping destination. But the bigger news may be that now you can keep all your content in one place, accessible from whatever Android device you happen to be using. (Sound familiar?) For fans of the existing Market, the change shouldn't be too painful. Your Android Market app will be renamed "Google Play Store."

In the U.S., music, movies, books and Android apps are available in Google Play. In Canada and the U.K., we’ll offer movies, books and Android apps; in Australia, books and apps; and in Japan, movies and apps. Everywhere else, Google Play will be the new home for Android apps.

According to Google, Android 2.2+ users will see the change "over the coming days." [youtube=http://www.youtube.com/watch?v=GdZxbmEHW7M]
