Sky is ensuring that you'll have some TV to binge on once all of that turkey's been polished off. It's updated the Sky+ app to include on-demand listings, letting you set programs to download to your Sky Box remotely. That way, if you're trapped upstairs, you can tee-up a half-day's worth of Game Of Thrones to make leaving the TV room worth your while. That said, if you just want to watch the shows while you're pretending to shoot the breeze with your relatives, there's always Sky Go.
Update: Sky has added that remote downloading only currently works while at home (presumably on the same network), but it's planning to add a roaming functionality at a later date.
