HBO’s Internet video service, HBO Go, is now available on Sony Computer Entertainment America’s PlayStation 3 consoles — but it still isn’t available for the newer PS4.

According to Sony, about 25 million PlayStation 3 consoles are in use in the U.S. Netflix — which has modeled itself on HBO and likes to compare itself to the premium cabler — has been available on the PlayStation 3 since 2009, and was one of 11 entertainment apps available on the PlayStation 4 at launch in November.

An update for PS3 users adding HBO Go will be available later Tuesday, SCEA senior VP of biz dev Phil Rosenberg said in a blog post. He added that the company is “working diligently with HBO” to port the app to PS4 but did not offer an ETA. HBO announced plans to bring the service to the videogame consoles earlier this year.

HBO Go already has the broadest device support among cable or broadcast TV networks, currently available on 12 platforms: PCs, Macs, iPhone, iPad, Android smartphones and tablets, Apple TV, Roku, Google Chromecast, Microsoft Xbox 360, Amazon Kindle Fire and Samsung Smart TVs.

HBO Go provides access to all of the network’s current and past original series, along with movies, documentaries and specials. The apps are free to download but to watch video, users must have an HBO subscription through a participating cable, satellite or telco TV provider.
