Twitter already put forward the idea of a social media “DVR,” that might let you “playback” tweets, and see what was being talked about at a certain time. It seems Zeebox wasn’t about to wait around for that to happen and took the initiative, bundling a similar feature into its latest update. The second-screen app will now recognise when you’re watching something after the fact, and resurrect the tweets that went along with it, as if it were live. Great for seeing what your tweeple were thinking at the time. Still won’t protect you from any Downton-eque spoiler debacles, sadly.
