Interactive Systems Corporation (styled INTERACTIVE Systems Corporation, abbreviated ISC) was a US-based software company and the first vendor of the Unix operating system outside AT&T, operating from Santa Monica, California. It was founded in 1977 by Peter G. Weiner, a RAND Corporation researcher who had previously founded the Yale University computer science department^[1] and had been the Ph.D. advisor to Brian Kernighan, one of Unix's developers at AT&T.^[2] Weiner was joined by Heinz Lycklama, also a veteran of AT&T and previously the author of a Version 6 Unix port to the LSI-11 computer.^[2]

ISC was acquired by the Eastman Kodak Company in 1988,^[3] which sold its ISC Unix operating system assets to Sun Microsystems on September 26, 1991.^[4] Kodak sold the remaining parts of ISC to SHL Systemhouse Inc in 1993.^[5]

Several former ISC staff founded Segue Software which partnered with Lotus Development to develop the Unix version of Lotus 1-2-3^{[citation needed]} and with Peter Norton Computing to develop the Unix version of the Norton Utilities.
