Google unveiled Google Play on Tuesday, a grand plan to unify all the media it serves up from various portals to one recognizable brand identity and location. Call it Google’s iTunes moment.

Instead of separating media by category — Google Music, Android Market, Google Books — all of Google’s disparate sources will be accesible from a very iTunes-like storefront, accessible via the web or through apps on Android smartphones and tablets.

“This is about going beyond just Android,” said Google engineering director Chris Yerga in an interview.
