Netflix offers $1 million for a better review

From Cnet:

Netflix, the popular online movie rental service, is planning to award $1 million to the first person who can improve the accuracy of movie recommendations based on personal preferences.

To win the prize, which is to be announced Monday, a contestant will have to devise a system that is more accurate than the company's current recommendation system by at least 10 percent. And to improve the quality of research, Netflix is making available to the public 100 million of its customers' movie ratings, a database the company says is the largest of its kind ever released.
