Zeditron Industries is a corporation originally specializing in fiber optic host channel adapters, owned by Adrian Conrad, who was smart enough to diversify before the market bottomed out. Now Zeditron is responsible for everything from shipyards to sportswear factories.
Conrad used Zeditron Industries in order to obtain a Goa'uld symbiote and capture Major Samantha Carter in the hopes of finding a cure for his illness with her memories of Jolinar of Malkshur, in conjunction with the creature's natural healing abilities. (SG1: "Desperate Measures")
A subsidiary of Zeditron is Immunitech Research, which orchestrated a mass-cloning of the Goa'uld symbiote. (SG1: "Nightwalkers")
