Cloud-gaming pioneer OnLive has announced that it will be introducing its instant-play games service in the UK on 22 September. Originally launched in the US last summer, the technology allows users to play well-known titles via a broadband connection without having to initially download the entire game. Instead, the code is stored on OnLive’s servers and the action is streamed in real-time to the user’s computer, TV or tablet device via the internet, like a YouTube video. Keith Stuart/The Guardian.
