Colson Industries is a large multi-national conglomerate created by an American businessman named Alec Colson.
Colson Industries aided in the Antarctica cleanup of wrecked Goa'uld and Earth craft that had recently engaged in battle over the Atlantis outpost, though they were not informed that most of the debris was of alien origin.
Colson Aviation developed the multi-engine control (M.E.C.) systems for the F-302 fighter-interceptor.
While Alec Colson was being told the truth about the Stargate program, it was revealed that there were financial irregularities at Colson Industries. The stock fell drastically, prompting a trading freeze at stock exchanges. The United States Congress provided aid and the company survived. (SG1: "Covenant")
