On-demand content refers to media that can be accessed at any time, rather than being tied to a specific broadcast schedule. This includes services like Netflix, YouTube, and Spotify, where users can choose what they want to watch or listen to whenever they prefer. This type of content is popular because it offers flexibility and convenience, allowing people to enjoy their favorite shows, movies, or music on their own terms. With the rise of smartphones and high-speed internet, on-demand content has become a significant part of modern entertainment consumption.
