Video-on-Demand (VOD) is a technology 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, computers, tablets, and smartphones. Users typically pay for individual titles or subscribe to a service for unlimited access. This flexibility has transformed how people consume media, making it more convenient and personalized.
