Google's digital marketplace for mobile applications, music, movies and books is unifying under a new name , "Google Play". Beginning Tuesday, the Android Market will be known as the Google Play Store. Google's eBookstore and recently launched music service will also be part of the Google Play Store. The same selection of books, music and movies had already been available on Android Market.

Google Play is entirely cloud-based so all the music, movies, books and apps are stored online.

On the Android phone or tablet, Google will be upgrading the Android Market app to the Google Play Store app over the coming days. Users' videos, books and music apps (in countries where they are available) will also be upgraded to Google Play Movies, Google Play Books and Google Play Music apps. The music, movies, books and apps users have purchased will continue to be available to them through Google Play - simply log in with their Google account.

To celebrate, Google will be offering a different album, book, video rental and Android app at a special price each day for the next week in its "7 Days to Play" sale. In the U.S., today?s titles include the collection of top 40 hits Now That's What I Call Music 41, the popular game Where's My Water, the novel Extremely Loud and Incredibly Close and the movie Puncture for just 25 cents each. In addition, users will find collections of hip-hop, rock and country albums for $3.99 all week, detective novels from $2.99, movies from 99 cents, and some favorite apps from 49 cents.

In the U.S., music, movies, books and Android apps are available in Google Play. In Canada and the U.K., Google will 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.

Google is trying to establish a one-stop shop that can satisfy everyone's digital desires, whether they are on a mobile device or a desktop computer's Web browser.
