It hasn't hit Sony's PlayStation 4 yet
HBO Go is now available on Microsoft’s Xbox One gaming console.
The online streaming service rolled out on the next-gen console Thursday, according to a Microsoft blog post. HBO Go is already available on the Xbox 360 and Sony’s PlayStation 3, but hasn’t yet arrived on the PS4.
Currently, you’ll need a cable subscription to use HBO Go. However, in 2015, the cable network is planning to launch a standalone online version of its channel that Internet users can subscribe to without paying for cable.
