A while back, Apple got to announce exclusive access to HBO's standalone application called Now that lets users watch content without a pre-existing subscription to the service. Of course we were all jealous, but today, that jealousy ends. Sundar Pichai just announced at Google I/O 2015 that HBO Now will be available on Android "across all devices."
That last bit is pretty important, because that means Android phones, tablets, and Android TV - just like how the service was released for Apple devices.
Unfortunately, there's no word as to when Now will hit the Store (but I would look for it soon). As far as price is concerned, the service costs $15/month. Now I can finally catch up on this season of Game of Thrones. Sweet.
