"Both the channel-centric reality of TV and its ephemeral nature are artifacts of the distribution bottleneck of cable broadcast. TV is still in the era of limited shelf space, while the lesson of the Long Tail is that more is always better. The growth of cable capacity over the past decade pales next to the growth in video creation over the same period and the size of the potential microaudiences for anything and everything. TiVo may have helped by at least taking the tyranny of time out of the equation, but we are nowhere near the iTunes model of being able to download everything ever made, anytime. "
