Google is rebranding as Google Play. The Android Market, Google Music and the Google eBookstore all now redirect to play.google.com. In the coming days, the Android Market app for smartphones and tablets will become the Google Play Store, according to a company blog post.

Today we’re eliminating all that hassle with Google Play, a digital entertainment destination where you can find, enjoy and share your favorite music, movies, books and apps on the web and on your Android phone or tablet. Google Play is entirely cloud-based so all your music, movies, books and apps are stored online, always available to you, and you never have to worry about losing them or moving them again.
Soon Google will be rolling out the Google Play Store to Android devices to replace their current Android Market builds. Any content purchased during the Android Market era will be retained and available via Google Play.
