The term time shifting used to be about personal DVRs and avoiding ads and separating appointment television - like sports games or the stuff kids like and lunch rooms talk about - from the rest of television, but for me, personally, it's beginning to mean something else: When is cultural product X available on the service I'm hooked into. So, many films premiere when I can get the DVD on Lovefilm and albums are released when they show up on Spotify.
This all comes at a loss of coherence, of course, but a lot of that is regained as the cultural artifacts become linkable talking points in online media.
