Matt Haughey‘s wonderful PVRBlog pointed to an interesting piece today: “Ten things that Microsoft and TiVo must each do to win the living room” by Thomas Hawk.
One thing that is discussed: the ability to record radio shows. I think this would be very perilous for most of radio, but something that seems primed for such a service is XM Radio. As I noted in the comments on PVRBlog, XM routinely promotes shows well in advance of the actual air date, indicating that at least some of the shows are programmed far in advance. A nearly-always-on PARR would have to be used for request-oriented stations.
It’s something that would, I think, really have potential.
