Sony has unleashed VidZone TV on PlayStation 3.
This offers over 100 pre-programmed, telly-style music channels to watch for free.
Apparently the idea is to do away with the need to spend time building playlists. You simply pick a themed-channel - seventies, eighties, hip-hop, dance, etc. - and let it play.
Previously VidZone required you search and compile your own on-demand playlists and put in a bit of effort. You can still do that, but that would be like actually walking around a supermarket instead of ordering online! Idiot!
