I-CON (short for "Island CONvention") was a yearly fan convention, held on the campus of the State University of New York at Stony Brook on Long Island, in Suffolk County, New York. First held in 1982, I-CON became a very eclectic convention. The programming there included things normally found at different types of convention, like speeches by and talks with science fiction authors, extensive gaming, Anime fandom, comics fandom, furry fandom, multiple movie showings, and medieval programming, as well as live performances. There was also a science track discussing recent developments in various branches of science and exploring the real science behind science fiction technologies.
I-CON was jointly held by ICON Science Fiction, Inc., a tax-exempt educational foundation, and the I-CON Campus Chapter of Stony Brook.
