Ok, I have been of two minds about the music and film industries regarding filesharing. Today is when I have decided they have lost their marbles.

Tactics like this - night-vision goggles in movie theatres and 'an hourlong class for fifth through ninth graders on the history of copyright law and the evils of online file sharing' are seriously off base. You cannot build a business on coercion and brainwashing (contrary to popular belief). A business model is just that - a model. When reality diverges seriously from the model, you had better get a grip on reality - not try and adjust reality to the model.

Of course, the music industry shows no sign of understanding any of this. In fact, they are going to most likely attempt to keep prices up.

Lesson: great strategy is at least half economics, at least half understanding and responding to shifts in consumer needs, and at least half harnessing (preferably discontinuous) innovation. Yes, I know that's three halves - the point is that whole should be more than the sum of the parts. Think of what video did for the film industry - when they got their strategy (kind of) right.
