Vieo installation is a contemporary art method that combines video technology with installation art. It is an art form that utilizes all aspects of its surrounding environment as a vehicle of affecting the audience. Its origins tracing back to the birth of video art in the 1970s, it has increased in popularity as the means of digital video production have become more readily accessible. Today, video installation is ubiquitous, visible in a range of environments--from galleries and museums to an expanded field that includes site-specific work in urban or industrial landscapes. Popular formats include monitor work, projection, and performance. The only requirements are electricity and darkness.
