Video on demand (VOD) are systems which allow users to select and watch/listen to video or audio content when they choose to, rather than having to watch at a specific broadcast time. IPTV technology is often used to bring video on demand to televisions and personal computers.

Television VOD systems can either stream content through a set-top box, a computer or other device, allowing viewing in real time, or download it to a device such as a computer, digital video recorder (also called a personal video recorder) or portable media player for viewing at any time. The majority of cable- and telco-based television providers offer both VOD streaming, including pay-per-view and free content, whereby a user buys or selects a movie or television program and it begins to play on the television set almost instantaneously, or downloading to a DVR rented from the provider, or downloaded onto a PC, for viewing in the future. Internet television, using the Internet, is an increasingly popular form of video on demand. VOD can also be accessed via desktop client applications such as iTunes.

Some airlines offer VOD as in-flight entertainment to passengers through individually controlled video screens embedded in seatbacks or armrests or offered via portable media players. Some video on demand services such as Netflix use a subscription model that requires users to pay a monthly fee to access a bundled set of content. Other services use an advertising-based model, where access is free for users, and the platforms rely on selling advertisements as a main revenue stream.
