The historic video magazine Radical Software was started by Beryl Korot and Phyllis (Gershuny) Segura, later joined by Ira Schneider, and first appeared in Spring of 1970, soon after low-cost portable video equipment became available to artists and other potential videomakers. Radical Software was an important voice of the American video community in the early 1970s; the only periodical devoted exclusively to independent video and video art at the time when those subjects were still being invented. Issues included contributions by Nam June Paik, Douglas Davis, Paul Ryan, Frank Gillette, Beryl Korot, Charles Bensinger, Ira Schneider, Ann Tyng, R. Buckminster Fuller, Gregory Bateson, Gene Youngblood, Parry Teasdale, Ant Farm, and many others.
Eleven issues of Radical Software were published from 1970 to 1974, first by the Raindance Corporation and then by the Raindance Foundation with Gordon and Breach Publishers.
