In 2009 Netflix held a contest challenging teams of developers to create an algorithm to increase the accuracy of its film recommendations by 10 percent. The award was $1 million, and it turns out Netflix pretty much flushed that money down the drain. The company doesn't use the winning algorithm. So, why?
Remember the whole Netflix/Qwikster debacle from a few months back? After making some truly blockheaded moves, Netflix backed off and undid a bunch of what got them in trouble. Now they have finally announced that the $7.99 DVDs by mail only plan is back, returning things to where they were six months ago.
