    So, what is Netflix Prize? In short, it's a competition held by Netflix who offered $100 millions to the winner who can improve Netflix algorithm system by 10%. And, as you can see in the video, team Bellkor, which consisted of three researchers from AT&T Labs, won the final prize with the 10% improvement of the original algorithm.
