Weyland-Yutani is primarily a technology supplier, manufacturing synthetics, spaceships and computers for a wide range of industrial and commercial clients, making them a household name.

Weyland-Yutani also has numerous non-manufacturing interests; the company has extensive assets in interplanetary shipping and transport, and is one of the corporations that operates human colonies outside the solar system through the Extrasolar Colonization Administration, which it owns or controls.

This huge conglomerate is always on the prowl for the best that space can offer, be it new planets suitable for colonisation or xenomorph tech for the military division.

Metacortex

Featured in: Matrix (1999)

MetaCortex (sometimes called MetaCortech) was a prominent software company in the Matrix that Neo worked for. It was referred to as being a "respectable software company" by Agent Smith. On what might have been his last day of work there, Neo, as Thomas Anderson, was being reprimanded by his boss, Mr. Rhineheart regarding his punctuality.

Blogger's note:

Matrix is one of my favorite science fiction movies because it refers to topics such as robotics, artificial intelligence, messianic figure, collapse of civilization, search for faith and internal conviction.

Cyberdyne Systems

Featured in: Terminator 2: Judgment Day (1991)

U.S. defence experts who try to eliminate human error from warfare by creating the self-aware Global Digital Defence Network known as Skynet. After obtaining a Terminator's remains, Cyberdyne reverse engineers its CPU and creates a powerful new microprocessor for weapons systems, becoming a major contractor for the US military.

Cyberdyne initially began as a manufacturing corporation at 18144 El Camino Real, Sunnyvale, California. Founded during early 1980s, its products are unclear, possibly computers or processors, but from the equipment in its factory and its high tech-sounding name, it seems possible that Cyberdyne might have been some sort of smaller parts producer for larger manufacturers of high tech equipment. As of 1984, the small company owned a factory.
