Netflix has announced a prize money of $1 Million for anyone who improves their movie recommendations engine. One catch though!

The Contest entry period commences on October 2, 2006 (00:00:00 UTC) and continues until the Grand Prize is awarded (the "Contest Term"). No additional registrations or Contest submissions of qualifying set predictions will be accepted after the close of the Contest Term. Netflix reserves the right to cancel the Contest after October 2, 2011 in its sole discretion.

So you might have to wait till 2011 to find the winner! :)
