For years, HBO GO was the main source for streaming HBO content, but only people who paid for (or knew people who paid for) HBO through the cable company were allowed to have it.
HBO NOW is open to anyone willing to pay $15 each month to stream their exclusive content.
Subscribers get access to blockbuster movies, music and HBO’s exclusive shows like “Game of Thrones.”
Apple and HBO collaborated and for time being, HBO NOW is available on only iOS devices. Android, Google and Amazon and next gen systems will get HBO NOW within a few months.
