The Gundam Series (ガンダムシリーズ Gandamu 
Shirīzu)
 is a metaseries of anime 
created by Sunrise studios that features giant robots
 (or "mecha")
 called "Mobile Suits" (MS); usually the protagonist's MS will carry the
 name Gundam.
The metaseries started on April 7, 1979, as a serial TV show called Mobile Suit Gundam. That first TV series has since 
spawned a franchise that has come to include works released in numerous 
media. Titles have appeared in the form of multiple television series 
and OVAs, movies, manga, 
novels and video games, among other modes. The story from the original 
1979 series has been considerably extended with sequels, prequels, side 
stories and alternate timelines. As a result, the title Gundam 
has become a collective term for the seven distinct but related 
timelines that can be pieced together from the stories that appear in 
the Gundam franchise. Generally speaking, the timelines do not 
intersect, but they do contain a few common elements such as the titular
 war machines called Gundam. However, all Gundam timelines
 and worlds, long after their own anime series, do eventually intersect 
and combine in the series Turn
 A Gundam.
The original timeline for the Gundam series was the Universal Century (UC) series, which included Mobile 
Suit Gundam (1979) and Mobile Suit Zeta Gundam (1985). 
Since the 1990s, alternative timelines have been produced and developed,
 including the Future Century, After Colony, After War, Correct
 Century, Cosmic Era, Anno Domini and Advanced Generation timelines.
As of January 21, 2008, the Gundam franchise is a 50 billion yen
 trademark.
 A year 2000 press release stated that retail sales of Gundam items had 
totaled $5 billion.
 In the 2008 ranking of average sales figures for anime copies sold in 
Japan (1970-2008 total sales figures averaged by episode), Gundam
 series were in four of the top five places: Mobile Suit Gundam 
ranked second, with Mobile Suit Gundam SEED Destiny
 third, Mobile Suit Gundam SEED fourth, 
and Mobile Suit Zeta Gundam fifth. Also, Mobile Suit Gundam Wing ranked 
18th and Mobile Suit Gundam ZZ ranked 
20th.
 Gunpla's (Gundam Plastic model) holds 90% of the
 Japan character plastic model market.
Academics in Japan have also viewed the series as inspiration, with 
the International Gundam Society being the first academic 
institution based on an animated TV series
