The explosion of digital video has created an unprecedented level of choice for viewers. Netflix VP of Product Innovation Todd Yellin and his team devised a way to sort through the choices and match viewers with the content they'll love. Using a system of tags, behavioral and implicit data, and sophisticated machine learning techniques, Netflix has been able to personalize the movie and TV-watching experience. As Yellin explains, this method not only allows Netflix to suggest the right content to its viewers, but also to piece together elements of a story to form original content and shows that Netflix can be confident will appeal to specific audiences.
