Video-on-demand (VOD) is a media distribution system that allows users to watch video content whenever they choose, rather than at a scheduled broadcast time. This service is commonly offered by platforms like Netflix, Amazon Prime Video, and Hulu, enabling viewers to select from a wide range of movies, TV shows, and documentaries. VOD can be accessed through various devices, including smart TVs, tablets, and smartphones. Users typically pay for individual titles or subscribe to a service for unlimited access. This flexibility has transformed how audiences consume media, making it more convenient and personalized.
