Every now and then, the business world presents us with a lab experiment that we can observe in realtime. Netflix's announcement that it is splitting off its DVD-by-mail business from its streaming business is just such an experiment. The DVD business will now go by the name Qwikster, and the streaming business will stay under the Netflix brand. It is Clayton Christensen's innovator's dilemma incarnate, and Netflix is very publicly trying to solve it. Like its 60% price increase did earlier this year, this move is understandably causing consternation amongst some customers. It's a bold move, one that will cost them in the near term, but Netflix I'm sure has done the calculus and is looking at the endgame 5-10 years out, not 5-10 months.
