Wikipedia Reference Information
Gundam (????, Gandamu?) is one of the longest running series of anime featuring giant robots or mecha. Gundam is the collective term for the Universal Century (UC) series like Mobile Suit Gundam and series in alternative timelines, such as Gundam Wing, made by Sunrise Inc. The name "Gundam" itself stems from a variety of theoretical sources, most commonly attributed to a need to conform with common giant robot naming conventions during the 1970s.
