None of this is meant to discredit Rudolph’s recognition of the value of context, which is likely to be the biggest challenge for the future of the living room, so to speak. Several years ago I was told that Amazon’s biggest search problem was in their Music “store,” because too many search requests would yield either way too much (mostly of the wrong thing) or nothing at all. This is sort of the “24″ problem blown up to an even larger scale.

Context is as much social as it is “semantic,” however. Graham Button talks about the problems of introducing a new technology in a workplace; and the problem that most concerns him is that any work setting has its own “immutable work practices” (his words) before the new technology is introduced. If the learning curve for the new technology does not take those immutable practices into account, the new technology many lower productivity rather than raise it.

So it is with home entertainment. However poorly it may have been designed, the Comcast box has now been around so long that a whole barrage of immutable practices have formed around it. Those practices would drive Nielsen (and probably most of your readers) crazy; but, like it or not, they are now part of the context of the consumer market. The path to the “Future of Media” will have to take them into account, which means that it will probably have any number of twists and turns that those of us with “technological common sense” cannot possibly anticipate!
