That means Amazon Prime subscribers will be able to see shows that
have already run on HBO, like “The Sopranos” and “The Wire.” And
they can also watch older seasons of some shows that are still on
the air, like “Girls,” three years after they air.
It’s the first time HBO has offered access to its catalog via a
streaming video service that’s not its own HBO Go. And it gives
Amazon an important bragging right/differentiation point as it
tries to gain ground on rival Netflix.
People familiar with the deal say HBO did not shop the catalog to
Netflix or other potential Amazon rivals.
In short: you still need HBO Go to watch new shows, and the only way to get HBO Go is to pay for HBO with your cable service. But Fire TV is getting HBO Go, too, “targeting a launch by year-end”.
