Which work by Nam June Paik features a 51 channel video installation

The work by Nam June Paik that features a 51 channel video installation is "Electronic Superhighway." This installation is a significant piece in the history of video art, representing the interconnectedness of media and culture in the late 20th century.

"Electronic Superhighway" consists of dozens of monitors that are arranged to outline the contiguous United States, each displaying a variety of video content that reflects different aspects of American culture, including images and sounds specific to various states. The use of 51 channels emphasizes the overwhelming nature of information in modern society, highlighting how television and media shape our understanding of the world.

This immersive experience not only showcases Paik's innovative use of technology but also serves as a commentary on the influence of mass media on individual and collective identities. The integration of such a large number of video channels is emblematic of the concept of media saturation and the complexity of contemporary life, making it a pivotal work in exploring the relationship between technology and viewers in an increasingly digital age.
