Overview

ASCII Media Works was a Japanese publishing company and later a Kadokawa brand created on April 1, 2008, through the combination of ASCII Corporation and MediaWorks. The transaction legally continued MediaWorks, while ASCII's former president and chief executive, Kiyoshi Takano, became the first president and chief executive of the combined company. The merger joined ASCII's experience in computing, information technology, and specialist computer publishing with MediaWorks' established portfolio in anime, manga, light novels, video games, and entertainment magazines. The company's most visible consumer identity was the Dengeki brand, whose name means “electric shock.” Its magazine portfolio covered games, anime, manga, visual novels, hobbies, modeling, and related enthusiast subjects. Important titles included Dengeki Daioh and Dengeki G's Magazine, while Dengeki Bunko became the company's principal male-oriented light-novel imprint. The wider publishing operation also served female readers through publications and imprints such as Dengeki Girl's Style, Sylph, and Character Parfait. Alongside entertainment publishing, the company maintained ASCII's computing and information-technology heritage through titles such as Weekly ASCII and other PC- and enterprise-oriented publications. ASCII Media Works operated across several forms of intellectual property development. It published magazines, manga, light novels, general novels, and other books; organized awards intended to identify new writers, illustrators, and manga creators; and developed or produced video games based on properties appearing in its publishing catalog. These games were commonly visual novels or sound novels and were released for platforms including PlayStation 2 and Nintendo DS. The company's publishing ecosystem therefore connected magazines, books, contests, adaptations, and game releases rather than treating each format as a separate business. Its contests were an important talent-discovery mechanism. The annual Dengeki Taisho included the Dengeki Novel Prize for light novels and the Dengeki Illustration Taisho for illustrators. The company also operated the Dengeki Comic Grand Prix for original manga and related competitions over time. These programs gave ASCII Media Works a route for finding creators who could contribute to its imprints and media-mix properties. The company became part of the broader Kadokawa Group and worked alongside other Kadokawa publishing businesses. In April 2011, its video-game division was combined with the game divisions of Kadokawa Shoten and Enterbrain under Kadokawa Games. On October 1, 2013, ASCII Media Works ceased to exist as a separate kabushiki gaisha when it was merged with eight other companies into Kadokawa Corporation. Its publishing activities and recognizable imprints continued within Kadokawa, but ASCII Media Works no longer operated as an independent corporation.

History

ASCII Media Works originated in the Japanese publishing businesses of ASCII Corporation and MediaWorks. ASCII had built a reputation in computer publishing, personal-computer culture, information technology, and related specialist media. MediaWorks, meanwhile, developed a strong entertainment portfolio centered on anime, manga, light novels, games, and magazines aimed at dedicated fan communities. Their combination reflected the increasing overlap among publishing, internet and mobile services, entertainment franchises, and software. The two companies combined on April 1, 2008. Although MediaWorks legally absorbed ASCII and was the continuing corporate entity, the new company used the ASCII Media Works name and appointed Kiyoshi Takano, previously ASCII's president and chief executive, as its first president and chief executive. The resulting business retained the editorial and commercial strengths of both predecessors. It published computer and IT material inherited from ASCII while expanding MediaWorks' entertainment-oriented activities across magazines, books, manga, games, and related media. The Dengeki identity became the central consumer-facing pillar of the company. Dengeki magazines addressed games, anime, manga, visual novels, hobbies, plastic modeling, and other specialist interests. Dengeki Daioh and Dengeki G's Magazine were among the best-known titles. The company also maintained publications for female readers, including Dengeki Girl's Style, Sylph, and Character Parfait. In computing and business publishing, Weekly ASCII and other PC and IT titles preserved the company's connection to ASCII's earlier editorial domain. Books and imprints formed another major part of the operation. Dengeki Bunko, established before the merger in 1993, served as the principal light-novel imprint for male readers and became a significant source of adaptable intellectual property. Related labels included Dengeki Game Bunko, B-Prince Bunko, Jewel Books, MediaWorks Bunko, Mahō no Island Bunko, and later Dengeki no Shin Bungei. Manga publishing included Dengeki Comics, Dengeki Comics EX, and Sylph Comics. The company also used its Mahō no Island relationship to publish novels originating from mobile-phone web fiction. ASCII Media Works supported this publishing system with recurring creator competitions. Dengeki Taisho included awards for light-novel manuscripts and illustrations, while the Dengeki Comic Grand Prix recognized original manga. These programs helped the company identify new authors and artists and supported a pipeline from submissions to books, magazines, adaptations, and games. The company also developed and produced games, particularly visual novels and sound novels based on properties connected to its publishing business. Releases appeared on platforms such as PlayStation 2 and Nintendo DS, and the company used labels including Dengeki SP and DS Dengeki Bunko for selected games and lower-priced reissues. This activity complemented, rather than replaced, its publishing focus. In April 2011, the video-game division was merged with the game divisions of Kadokawa Shoten and Enterbrain into Kadokawa Games. The broader corporate integration was completed on October 1, 2013, when ASCII Media Works and eight other companies were merged into Kadokawa Corporation. From that point, ASCII Media Works stopped operating as a separate corporation and continued as a Kadokawa internal brand or organizational unit. Its Dengeki publications and imprints remained associated with Kadokawa's Japanese publishing and media business.
