Why Digital TV Won't Kill Discs Soon
It has been theorized that digital TV and downloadable video will rapidly destroy the DVD market, to the extent everyone has broadband. I don't think this is going to happen as rapidly as people thing, because even ignoring some of the other economic advantages of physical media (like the sense of ownership), the economics of the bits that make up the video are different for discs and broadcasting/downloading in some important ways, resulting in a quality advantage for the discs.
