Netflix Offers $1 Million Prize for Improved Recommendation System | Digital Media Wire
Los Gatos, Calif. - Online DVD rental service Netflix on Monday launched a contest that will award $1 million to whomever can make its personalized movie recommendations 10% more accurate. The company offers a library of 65,000 DVD titles to its more than 5 million members, and provides movie recommendations to subscribers based on their past preferences. "Recommendation systems covering a wide variety of categories will play an increasingly significant commercial role in the future," said Netflix CEO Reed Hastings. "Right now, we're driving the Model T version of what is possible. We want to build a Ferrari and establishing the Netflix Prize is a first step." The company made available 100 million anonymous movie ratings submitted by its subscribers for use in the contest. If no one is able to achieve a 10% improvement in accuracy over the current Netflix recommendation system this year, the company said it will award $50,000 to whoever comes closest annually until someone wins the grand prize.
