Google Play also is a content library and ecosystem that is accessible on more platforms than almost any other.
Born as the Android Market, it's grown from just a home for apps and is now the one-stop shop for applications, books, movies, music, TV shows — basically anything and everything that you can buy and use on your Android phone or tablet.
Google Play store is where Google wants you to buy apps, movies, music, and even books, if you haven't been completely brainwashed by free apps like Candy Crush and Clash of Clans.
Google Play store goes far beyond Android as a content provider, however, which is why Google changed the name back in 2012 from Android Market to Google Play.
It's for far more than just Android.
The videos from Google Play Movies & TV are available in the app on either Android or iOS, as well as in YouTube.
Likewise, Google Play Music and Books are accessible on iOS, Android, and through the Chrome browser.
And if you're on a computer with the Chrome browser, almost all of Google Play's content is available to you, save for apps, of course.
