Video art is a type of art which relies on moving pictures and comprises video and/or audio data. (It should not however be confused with television or experimental cinema). Video art came into existence during the 1960s and 1970s, is still widely practiced and has given rise to the widespread use of video installations.
Video art is named after the video tape, which was most commonly used in the form's early years, but before that artists had already been working on film, and with changes in technology Hard Disk, CD-ROM, DVD, and solid state are superseding the video tape as the carrier. Despite obvious parallels and relationships, video art is not film.
Many of the early prominent video artists were those involved with concurrent movements in conceptual art, performance, and experimental film. These include Americans Vito Acconci, John Baldessari, Peter Campus, Doris Totten Chase, Dan Graham, Joan Jonas, Bruce Nauman, Martha Rosler, William Wegman, and many others. There were also those such as Steina and Woody Vasulka who were interested in the formal qualities of video and employed video synthesizers to create abstract works.
Although it continues to be produced, it is represented by two varieties: single-channel and installation. Single-channel works are much closer to the conventional idea of television: a video is screened, projected or shown as a single image, Installation works involve either an environment, several distinct pieces of video presented separately, or any combination of video with traditional media such as sculpture. Installation video is the most common form of video art today. Sometimes it is combined with other media and is often subsumed by the greater whole of an installation or performance. Contemporary contributions are being produced at the crossroads of other disciplines such as installation, architecture, design, sculpture, electronic art, VJ (video performance artist) and digital art or other documentative aspects of artistic practice.
