In 1979, Yoshiyuki Tomino created Mobile Suit Gundam, a futuristic-like TV series. The first time it aired, it did not do well. Then, in some Star Trek-like coincidence, the popularity of it soared after the end of the original run. A huge metaseries was born from that TV show.

The Mobile Suit Gundam 00 television series was created by Yosuke Kuroda as writer and Seji Mizushima as director. It aired for 50 episodes between 2007 and 2009.

The duration of Mobile Suit Gundam is 2.23 hours.
