Mobile Suit Gundam is a series that began in 1979 created by a team of animators led by Yoshiyuki Tomino of Sunrise Studio. Since 1979 there have been over 58 animated television series along with several light novels, manga, and video games across the decades.
What came from this was a deeper subculture surrounding the development of plastic model kits referred to as "Gunpla" and sold as scale models of the series' titular mobile suit mechs.
