At first there was Gakai, a cloud gaming technology that works on almost any device, including smartphones. The technology employs servers and remote data centers to run the games, so it did not require too much from gaming hardware. The servers run the games and streamed compressed video frames to make them run on devices.
Sony purchased Gakai and improved on it. The result is PlayStation Now, a new service announced by Sony at CES 2014. PlayStation Now offers streaming of PlayStation games to Sony gaming devices like the PS4, PS3 and PlayStation Vita. But this is not the extent of compatible devices. PlayStation Now also works on televisions, tablets, and smartphones.
Sony’s PlayStation Now will first roll out on PlayStation 4 and PlayStation 3 and eventually, it will also be available on the PlayStation Vita. According to Sony, most 2014 models of Sony Bravia TVs will support PlayStation Now. For features, PlayStation Now is expected to stream full games and progress can be saved in the cloud. Users will also be able to rent games or pay for a subscription service. PlayStation Now will also have support for online multiplayer and trophies.
