What is video-on-demand?
Video-on-demand (VOD) is a technology that delivers video content, like movies and TV shows, directly to individual customers for immediate viewing.
In cable television VOD systems, video content is stored as compressed digital files on a centralized server. Customers can use a cable set-top box to navigate a programming menu and make a selection, which may be available for free or for a fee. The server then immediately begins streaming the program, which the viewer can pause, fast-forward, rewind, or stop and resume later. These programs are sometimes available only for a short period.

How is video-on-demand different from regular TV?
Video-on-demand (VOD) and regular TV differ in how viewers access content. Traditional TV broadcasts programs at scheduled times, whereas VOD allows viewers to select and watch content whenever they want. In a VOD system, video content is stored on a central server, and users can navigate a menu via a set-top box to make their selections. They can also pause, fast forward, rewind, or stop and later resume the program. VOD systems may be cable-based, download-based, or streamed over the Internet. The rise of Internet-based VOD has even led some viewers to cancel their cable subscriptions in favor of Internet streaming.

Why does video-on-demand require an internet connection?
Video-on-demand (VOD) relies on an internet connection to deliver video content directly to individual customers for immediate viewing. In a typical VOD system, video content is stored as compressed digital files on a centralized server. When a customer selects a program through a programming menu, the server streams the program to them.
Internet-based VOD has become increasingly common, offering users access to extensive programming libraries. Streaming services like Netflix and YouTube use content delivery networks (CDNs) to distribute video segments to viewers with minimal delay. CDNs consist of geographically dispersed servers that cache video content, ensuring efficient delivery. The numerous options for Internet VOD have even led some viewers to cancel cable in favor of Internet streaming.

How has video-on-demand changed the way people watch movies and TV shows?
Video-on-demand (VOD) has revolutionized media consumption by providing instant access to a vast library of movies and TV shows. Unlike traditional broadcasting, VOD allows viewers to select and watch content whenever they want, offering unprecedented flexibility.
The rise of streaming services like Netflix and YouTube has further fueled this shift, with many viewers now "cutting the cord" and opting for internet streaming over cable television. This transition has led to intense competition among streaming companies, resulting in a "streaming war" where companies differentiate themselves through exclusive content.

video-on-demand (VOD), technology for delivering video content, such as movies and television shows, directly to individual customers for immediate viewing.
In a cable television VOD system, video content is stored on a centralized server in the form of compressed digital files. A customer navigates a programming menu via the cable set-top box and makes a selection, available either at no cost or for a charge. The server immediately begins streaming the program. The viewer may pause, fast-forward, rewind, or stop and later resume the program. Sometimes the program will be available for viewing only for a short set time period. VOD systems may also use a download-based model, in which the program is stored on a hard disk in the set-top box, or they may transmit over the Internet to a personal computer. Satellite television services, which broadcast the same signal over an entire service area, cannot accommodate true VOD, though they often offer Internet VOD.
Cable providers experimented with VOD in the 1990s, but the services failed to achieve much success until the next decade, when equipment and bandwidth became less expensive and content providers began allowing more programming to be offered by VOD. By the middle of the decade, VOD had largely supplanted schedule-driven pay-per-view service on cable systems, and by 2010 most television networks were offering many of their programs on VOD.
In the same time frame, Internet-based VOD grew more pervasive in the video-rental market, allowing customers immediate access to an expansive library of programming at the click of a button. New development efforts focused on bridging the gap between Internet and television sets, allowing online rental services to compete with cable providers in bringing content to customers’ television screens. Subscription services such as Netflix and Amazon Prime allowed users to stream video for a monthly fee. The video site YouTube also hosted many videos that could be streamed on demand. In the early 21st century more than 70 percent of Internet traffic was streaming video. The many options available for Internet VOD have even led some viewers to “cut the cord”—that is, to reject cable television in favour of Internet streaming.
