Founding and early history (1987–1993)

Production I.G was founded on December 15, 1987, by producer Mitsuhisa Ishikawa and character designer Takayuki Goto.^{[Web 2]} The letters I and G refer to Ishikawa and Goto's initials, respectively.^[1] According to Ishikawa, using initials was Goto's idea.^[2] Prior to the founding of Production I.G, Ishikawa worked for Tatsunoko Production where he was tasked to produce the 1987 series Zillion. Ishikawa gathered staff to form the "Tatsunoko Production Branch" studio that worked on the Zillion series.^{[3][Web 3][4]} After completing the production of Zillion, Ishikawa founded a studio to prevent the staff from dispersing naming it "I.G Tatsunoko."^[3][4][5] Ishikawa would later say that he added "Tatsunoko" as he thought this could lead to more work for the studio.^[2] Goto previously founded and ran studio "Chime," but found it difficult to manage others and wanted to focus more on animation leaving Ishikawa to take care of management. Animator Kazuchika Kise also joined the studio early on.^[4]

Ishikawa said that the studio's primary goals were to "concentrate on projects led by lively young creators who would support the anime industry in the future"^[2] and creating anime feature films that would appeal to wider audiences rather than strictly to otaku.^[6] Takashi Nakamura, Koichi Mashimo, Hiroyuki Okiura, Kazuchika Kise, Mizuho Nishikubo and Mamoru Oshii helped out in production during the studio's beginnings as a subcontractor while Kyoto Animation's Hideaki Hatta invested in the company.^[2]

As I.G Tatsunoko, the studio worked on numerous original video animations (OVAs) such as The Heroic Legend of Arslan^{[Web 4]} and Please Save My Earth.^[7] In 1989, the studio helped produce the feature-length cinematic anime Patlabor: The Movie together with Studio Deen^[8] and, in 1993, the studio produced the sequel Patlabor 2: The Movie.^[9] The studio changed its name to the current "Production I.G" in September of 1993.^{[Web 5]}

Expansion of the studio (1995–2008)

After the studio's name change, Production I.G expanded its work into films and television series. In 1995, the studio produced the 1995 film Ghost in the Shell directed by Mamoru Oshii.^[10] The film would go on to spawn a media franchise that includes a sequel film released in 2005^[11] and television series that ran from 2002 until 2005.^[12] According to Ishikawa, Ghost in the Shell was a "turning point" for Production I.G as it allowed the studio to break away from subcontracting work to become more involved with productions.^[4]

During this time, the studio also produced the 1999 film Jin-Roh: The Wolf Brigade directed by Hiroyuki Okiura^[13] and produced the animated sequences in Quentin Tarantino's Kill Bill Vol. 1.^[14] The studio began branching out into the production of original television series starting with Blood+,^[15] an anime series based on its 2000 film Blood: The Last Vampire.^[16] Production I.G also began its collaboration with the group Clamp adapting their manga series: xxxHolic into a television series in 2006^[17] and producing the 2011 anime series Blood-C which served as a sequel to Blood+.^[18]

Apart from its animation production, Production I.G also began its expansion, forming subsidiary studios: studio Xebec in May 1995^[19] and Bee Train, founded by Koichi Mashimo in early 1997, as a studio that could work on small productions and "nurture" the creative spirit of its staff members.^[20] In 2006, Bee Train became an independent studio and Ishikawa stepped down as an executive in the company.^[21]

The studio also underwent several structural changes. In April 1998, it incorporated to become "Production I.G, Inc." and in September 2000 merged with "Ing", a company Production I.G established in June 1990.^{[Web 5]} Ing served as a means of easier handling of production matters.^[4] On July 4, 2007, the company announced a merger with Mag Garden, forming a new holding company named IG Port which became the parent company of Production I.G, Signal.MD and Xebec.^[22] Xebec remained part of IG Port until November 20, 2018, when it was sold to Sunrise. On January 12, 2018, Xebec's subsidiary, Xebeczwei, was given to Production I.G as a subsidiary renamed to IGzwei following the transfer.^[19]

Continued television work, leadership changes (2009–present)

After becoming an IG Port subsidiary, Production I.G continued its work on anime television series with original works and adaptations. In 2009, the studio produced its original series Eden of the East^[23] that was bookended with two theatrical films released in 2009 and 2010.^[24] In 2011, the studio produced the original series Guilty Crown directed by Tetsuro Araki.^[25] In 2012, the studio produced the Psycho-Pass television series.^[26]

Production I.G is closer to several divisions working under the same name (such as with Sunrise) than it is to being a single studio. These different studios are known as different "sections" in reference to the studio's Ghost in the Shell franchise. In 2011, Section 6 head George Wada and animation producer Tetsuya Nakatake approached Ishikawa with the intention of founding a new studio under Production I.G to allow for more creative freedoms and faster production processes than were available at I.G itself. On June 1, 2012, Wit Studio was founded, with the studio's first project being Attack on Titan, which I.G assisted in producing.^[27]

During this time, Production I.G produced a number of sports related anime series: Kuroko's Basketball, which ran for three seasons from 2012 until 2015,^[28] The Prince of Tennis II, which ran for a season in 2012,^[29] Haikyu!!, which ran for four seasons from 2014 until 2020^[30] and Aoashi, which ran for a season in 2022.^[31]

On June 5, 2017, Production I.G launched an anime streaming app called Tate Anime (Vertical Anime). The anime that were streamed on the app were series of shorts that had 10 3-minute long episodes each.^[32] In May 2018, it was announced that Tate Anime would be replaced with a new app called Anime Beans.^[33] On December 18, 2018, Anime Beans was launched worldwide, excluding China, with 10 titles available with English subtitles.^[34] The app ended service on March 31, 2023.^[35]

On June 25, 2022, Production I.G announced that current executive vice-president George Wada was to become President and CEO of the studio, while current President and CEO Mitsuhisa Ishikawa would become Chairman. The changes took effect on August 30, 2022.^[36]
