Mega-corporation

Megacorporation, or megacorp, a term popularized by William Gibson, derives from the combination of the prefix mega- with the word corporation. It has become widespread in cyberpunk literature. It refers to a corporation (normally fictional) that is a massive conglomerate, holding monopolistic or near-monopolistic control over multiple markets (thus exhibiting both a horizontal and a vertical monopoly). Megacorps are so powerful that they can ignore the law, possess their own heavily armed (often military-sized) private armies, hold "sovereign" territory, and even act as outright governments. They often exercise a large degree of control over their employees, taking the idea of "corporate culture" to an extreme. Such organizations as a staple of science fiction long predate cyberpunk, appearing in the works of writers such as Philip K. Dick (Do Androids Dream of Electric Sheep?, 1968), Thea von Harbou (Metropolis, 1927), Robert A. Heinlein (Citizen of the Galaxy, 1957), Robert Asprin (The Cold Cash War, 1977), Andre Norton (the Solar Queen novels) and David Weber ("the "Honorverse" novels).
