These two consoles are the first gaming platforms to provide access to HBO original programming in the U.S. PlayStation owners who want to take a break from Final Fantasy XIII can navigate over to the PlayStation Network Store purchase episodes of current HBO shows like True Blood. Or you can catch up on old favorites like Flight of the Conchords and The Wire instantly.
Unfortunately, not everything you'd want is ready yet (i.e. there are only two seasons of Entourage available so far). But Sony says that additional episodes and titles will be added weekly, so keep checking.
