Final answer:
Netflix uses collaborative filtering software to match movie titles with customer tastes, enhancing the personalized user experience and engagement.
Step-by-step explanation:
Netflix uses collaborative filtering software to match movie titles with customer tastes. Collaborative filtering is a technique where Netflix collects data about user ratings and preferences and combines it with data from other users to recommend movies that are likely to be of interest to a particular user. For example, if a user has rated several action movies highly, Netflix will recommend other action movies to them. This software helps Netflix garner a sustainable competitive advantage by personalizing the user experience and keeping users engaged with tailored recommendations.
