Korean-born artist Nam June Paik has died at age 74. He is credited with "inventing video art in the 1960s by combining multiple TV screens with sculpture, music and live performers. ... 'He really led the development of a new art form, bringing the moving image into the modern art world,' said John Hanhardt, senior curator of film and media arts at the Guggenheim." Paik also referred to an "electronic super highway" in a 1974 report, decades before the Internet entered widespread use. Although Paik moved to New York in 1964, his artwork was shown in his native country including at the 1988 Olympic Games in Seoul. The Nam June Paik Museum is currently in development in South Korea.
