How Netflix Decides What You'll Watch Next

It is sad to think that this much effort goes into quite possibly the worst recommendation system on the planet. Love Netflix. Hate its terrible recommendation system.

We know what you played, searched for, or rated, as well as the time, date, and device. We even track user interactions such as browsing or scrolling behavior. All that data is fed into several algorithms, each optimized for a different purpose. In a broad sense, most of our algorithms are based on the assumption that similar viewing patterns represent similar user tastes. We can use the behavior of similar users to infer your preferences.
