HBO jumps on the portable media bandwagon, releasing the below trailer for it's "HBO Go" app.
Unfortunately it won't be any use to you unless you already subscribe to the channel via your mother cable provider.
The service will give you access to HBO's entire library which consists of 1,400 episodes, movies and documentaries, says Venture Beat.
The app which will be available for iOS and Android devices comes out May 2.
