A vehicle entertainment system includes a video display unit, a camera, a communication interface, and a processor. The video display unit provides content to a user. The camera outputs a camera signal containing data representing the user's face. The communication interface communicate with a central content usage analysis computer. The processor processes the camera signal to identify facial features, compares the facial features to defined demographics rules, identifies user demographics based on the comparison of the facial features to the defined demographics rules, correlates the user demographics to a timeline of content consumed by the user through the video display unit to generate enhanced content usage metrics, and communicates the enhanced content usage metrics through the communication interface for delivery to the central content usage analysis computer.
