HBO has extended its new over-the-top service, HBO Now, beyond the Apple (NASDAQ: AAPL) constellation of IP devices, with Google (NASDAQ: GOOG) announcing at its developers conference Thursday that the product will soon be available for Android devices and Chromecast. Google says HBO Now will be available on these platforms via web browser. Availability for Google's Android TV program will occur over the summer, when HBO's three-month exclusive window with Apple expires, the company added.
