Slogan[1]SEGA Corporation.
Sega Corporation (株式会社セガ, Kabushiki-gaisha Sega, stylized as SEGA) is a Japanese video game and entertainment company headquartered in Tokyo, Japan. A subsidiary of Sega Sammy Holdings, the company develops, publishes, and owns several major game franchises, including Sonic the Hedgehog, Phantasy Star, Puyo Puyo, Super Monkey Ball, Virtua Fighter, Sakura Wars, Yakuza, Persona, Total War, Football Manager, and Angry Birds.[8]How Angry Birds broke the limits for mobile games.

[10]https://www.segasammy.co.jp/cms/wp-content/uploads/pdf/en/ir/ir_2021_web_all_en.pdf From 1983 until 2001, Sega also produced its own line of home video game consoles.
Sega traces its origins to coin-operated amusement businesses connected to Service Games and Rosen Enterprises. Service Games was originally founded to provide amusement machines for American military bases, while Rosen Enterprises imported coin-operated machines into Japan. The two lines of business came together in 1965, forming Sega Enterprises, Ltd. Sega achieved early arcade success with titles such as Periscope, later entered the home console market with the SG-1000 and Master System, and became one of the most prominent video game companies of the late twentieth century.
The company reached its greatest console success with the Sega Mega Drive, known as the Sega Genesis in North America. Following the release of Sonic the Hedgehog in 1991, Sonic became Sega’s mascot and one of the most recognizable characters in video game history. The success of Sonic and the Genesis helped Sega become a major competitor to Nintendo during the early 1990s, particularly in North America. Sega later released the Sega CD, Sega 32X, Sega Saturn, and Dreamcast, but declining hardware sales and financial pressure led the company to discontinue console manufacturing and focus on third-party software development.
Sega remains closely associated with arcade games, console and PC software, mobile titles, amusement machines, and entertainment venues. Its international branches include Sega of America and Sega Europe, while its development structure includes internal studios and major subsidiaries such as Atlus, Creative Assembly, Sports Interactive, Hardlight, Two Point Studios, and Rovio Entertainment. The company’s most prominent franchise, Sonic the Hedgehog, continues to serve as a central part of Sega’s global identity.

History[edit]
Origins and arcade success

Sega’s origins trace back to coin-operated amusement businesses established for American military markets. In May 1940, Martin Bromley, Irving Bromberg and James Humpert formed Standard Games in Honolulu, Hawaii, to provide amusement machines, including slot machines, for military bases. After World War II, the founders sold Standard Games in 1945 and established Service Games the following year, with the name reflecting the company’s military customer base.[11]. They Create Worlds: The Story of the People and Companies That Shaped the Video Game Industry, Vol. I: 1971–1982. CRC Press. . pp. 105. ISBN 978-0-429-75261-2
After slot machines were outlawed in United States territories in 1952, Bromley sent Richard Stewart and Ray LeMaire to Tokyo to establish Service Games of Japan, which supplied coin-operated slot machines to American bases in Japan.[12]IGN Presents the History of SEGA. IGN. . Archived version[13]. Meet the four Americans who built Sega. Kotaku. . Archived version The name “Sega”, an abbreviation of “Service Games”, was first used in 1954 on the Diamond Star slot machine.[14]. The Sega Arcade Revolution, A History in 62 Games. McFarland & Company. . pp. 3–6. ISBN 978-1-4766-3196-7
Service Games of Japan was dissolved on May 31, 1960, after investigations by the United States government into business practices connected to the company. On June 3, Bromley established Nihon Goraku Bussan and Nihon Kikai Seizō to take over its business activities. The companies purchased the assets of Service Games of Japan, with Kikai Seizō manufacturing slot machines under the Sega, Inc. name and Goraku Bussan, doing business as Utamatic, Inc., distributing and operating coin-operated machines such as jukeboxes.[14]. The Sega Arcade Revolution, A History in 62 Games. McFarland & Company. . pp. 3–6. ISBN 978-1-4766-3196-7[15]Sega and Utamatic Purchase Assets of Service Games. Billboard. . Vol. 72. Issue 34. p. 71[16]Service Games Inc. Bought By Sega and Uta Matic. Cashbox. . Vol. 21. Issue 51. p. 52 The two companies merged in 1964, retaining the Nihon Goraku Bussan name.[14]. The Sega Arcade Revolution, A History in 62 Games. McFarland & Company. . pp. 3–6. ISBN 978-1-4766-3196-7
A separate line of Sega’s history began with David Rosen, an American former United States Air Force officer stationed in Japan, who founded Rosen Enterprises in Tokyo in 1954. The company began as a photo booth business before importing coin-operated games into Japan. In 1965, Nihon Goraku Bussan acquired Rosen Enterprises, forming Sega Enterprises, Ltd. (株式会社セガ・エンタープライゼズ, Kabushiki gaisha Sega Entapuraizezu). Rosen became CEO and managing director, Stewart became president, and LeMaire became director of planning. Sega soon moved away from leasing machines to military bases and focused instead on coin-operated amusement machines.[12]IGN Presents the History of SEGA. IGN. . Archived version[17]Horowitz 2018, p. 7

Because many of Sega’s imported machines required maintenance, the company began manufacturing replacement parts, which helped lead it toward original game development.[18]Sega Arcade History. Enterbrain. . . pp. 20–23. ISBN 978-4-7577-0790-0 Sega’s first arcade electro-mechanical game was the submarine simulator ‘Periscope, released worldwide in the late 1960s. The game became successful in Japan and was exported to Europe and the United States, where it helped standardize the 25-cent-per-play arcade price. Its success encouraged Sega to continue producing original arcade titles.[19]Horowitz 2018, pp. 10–11[20]They Create Worlds: The Story of the People and Companies That Shaped the Video Game Industry, Vol. I: 1971-1982. CRC Press. . pp. 119–20, 188–91. ISBN 978-0-429-75261-2
In 1969, Sega was sold to Gulf and Western Industries, although Rosen remained CEO. Sega released Pong-Tron, its first video-based arcade game, in 1973.[21]Horowitz 2018, pp. 14–16 During the late 1970s, the company benefited from the arcade video game boom, with revenue exceeding US$100 million by 1979. Sega also acquired Gremlin Industries and Esco Boueki, a coin-operated game distributor owned by Hayao Nakayama, who was placed in a management role in Sega’s Japanese operations.[22]Horowitz 2018, pp. 21–23 By the early 1980s, Sega was one of the top five arcade game manufacturers in the United States, and its annual revenue reached $214 million.[23]Sega!. Businessweek. . . . . Archived version Notable releases from this period included Head On, Frogger, which Sega licensed from Konami, and Zaxxon, one of the earliest arcade games to use isometric graphics.[24]Horowitz 2018, pp. 24–26[25]Horowitz 2018, p. 36[26]Horowitz 2018, p. 48
Entry into the console market, management buyout, and arcade resurgence

Following a downturn in the arcade business in the early 1980s, Gulf and Western sold Sega’s North American arcade manufacturing organization and arcade game licensing rights to Bally Manufacturing in September 1983.[27]. What's New In Video Games; Taking the Zing Out of the Arcade Boom. The New York Times. . . . Archived version Sega’s Japanese subsidiary and North American research and development operation were retained by Gulf and Western. With the arcade market in decline, Nakayama pushed Sega to enter the home consumer market in Japan.[28]The Next Level: Sega's Plans for World Domination. Wired.
Sega developed the SC-3000 computer and, after learning that Nintendo was preparing the Family Computer, created its first home video game console, the SG-1000.[29]SG-1000. Retro Gamer. . Issue 163. pp. 56–61 The SG-1000 launched in 1983 and sold above Sega’s first-year expectations, but it was overshadowed by Nintendo’s Famicom, whose third-party software support helped it build a stronger library.[29]SG-1000. Retro Gamer. . Issue 163. pp. 56–61
In 1984, Rosen and Nakayama arranged a management buyout of Sega’s Japanese assets with financial backing from CSK Corporation. The assets were purchased for $38 million by investors led by Rosen and Nakayama. Isao Okawa, head of CSK, became chairman, while Nakayama became CEO of Sega Enterprises, Ltd.[30]Kent 2001 p. 343[31]Kent 2001 p. 494
Sega followed the SG-1000 with the Mark III, later rebranded as the Master System outside Japan. The Mark III launched in Japan in 1985, while the Master System was released in North America in 1986 and Europe in 1987. Although more powerful than the Famicom in some respects, it struggled in Japan and North America because of Nintendo’s strong market control and Tonka’s ineffective North American marketing. The system performed better in Europe and Brazil, where Tectoy continued supporting Master System hardware for many years.[32]Retroinspection: Master System. Retro Gamer. . Issue 44. pp. 48–53[33]. Playing at the Next Level: A History of American Sega Games. McFarland & Company. . pp. 6–15. ISBN 978-1-4766-2557-7[34]. Brazil Is An Alternate Video Game Universe Where Sega Beat Nintendo. Atlas Obscura. . Archived version
Sega also strengthened its arcade operations during the mid-1980s. Sega Europe opened in 1984, and Sega re-entered the North American arcade market in 1985 through Sega Enterprises USA. The release of Hang-On in 1985 and Out Run in 1986 marked a renewed arcade rise for the company, with both titles becoming major successes. Sega also introduced UFO Catcher in 1985, beginning a long-running line of crane machines that became especially prominent in Japan.
Mega Drive/Genesis, Sonic the Hedgehog, and mainstream success


Sega released the Sega Mega Drive in Japan in 1988 and in North America as the Sega Genesis in 1989. The system initially struggled in Japan but became a major success overseas, especially in North America. Sega of America, first under Michael Katz and later under Tom Kalinske, promoted the Genesis with aggressive marketing campaigns aimed at Nintendo, including slogans such as “Genesis does what Nintendon’t” and “Welcome to the next level.”
In 1991, Sega introduced Sonic the Hedgehog as a new flagship character and mascot. Sonic was designed and marketed as a faster, cooler alternative to Mario, and the release of Sonic the Hedgehog helped transform the Genesis into a major competitor to the Super Nintendo Entertainment System. The success of Sonic gave Sega a stronger global identity and helped the Genesis briefly outsell the Super Nintendo in the United States. Sonic the Hedgehog 2, released in 1992, became one of Sega’s most successful games, selling six million copies as of June 2006.[35]. A Detailed Cross-Examination of Yesterday and Today's Best-Selling Platform Games. Gamasutra. . Archived version
Sega expanded the Mega Drive platform with add-ons such as the Sega CD, which used CD-ROM media to support larger games, video sequences, and expanded audio. Its library included Sonic the Hedgehog CD, one of the system’s best-known titles. Sega later released the Sega 32X, an add-on intended to extend the Genesis hardware life with more advanced graphics. Although it sold well at first, the 32X suffered from limited software support, confusion with the upcoming Sega Saturn, and poor long-term sales.
Sega v. Accolade
In 1992, Sega lost the Sega v. Accolade legal case, which concerned independently produced software for the Mega Drive. Accolade had copied a small amount of Sega code while reverse-engineering the console to make unlicensed games. The ruling established that copyright did not extend to non-expressive software elements required for compatibility with a system. Sega had attempted to prevent unlicensed publishers from releasing Mega Drive games unless they paid licensing fees, partly by making the console reject cartridges that did not include a Sega trademark. Although Sega lost the case, later Sega systems continued to include hardware-based security requirements.
Arcade successes
Sega remained a major force in arcades throughout the early and mid-1990s. Virtua Racing became an important milestone for 3D racing games, while Virtua Fighter, released in 1993, was widely recognized as a major achievement in 3D fighting game design. The game used the Sega Model 1 arcade system board and helped establish the 3D fighting genre.
In 1994, Sega released Daytona USA, which became one of the most successful arcade racing games of its era. Other major arcade releases during the period included Virtua Cop and Star Wars Arcade. Sega also launched the Sega Channel, a cable-based subscription service that allowed Genesis owners to download and play games through a special cartridge adapter.
Saturn, 32X, and falling console sales

Sega released the Sega Saturn in Japan in 1994 and in North America in 1995. The Saturn used 32-bit hardware and was designed with strong 2D capabilities and arcade-style software in mind. It launched in the United States ahead of both the PlayStation and Nintendo 64, but its surprise launch strategy, high price, complex hardware, and weaker Western third-party support damaged its market performance.
The Saturn performed better in Japan, where it became Sega’s most successful home console. Its library included arcade conversions such as Virtua Fighter 2 and Sega Rally Championship, as well as titles such as Nights into Dreams…, Burning Rangers, Panzer Dragoon, The House of the Dead, Radiant Silvergun, Sakura Wars, Panzer Dragoon Saga, Grandia, and Shining Force III. Despite this, the console failed to match the PlayStation’s worldwide commercial momentum.
In 1997, Sega entered merger discussions with Bandai, but the plan was cancelled after disagreements between the companies. Around the same time, Sega announced that the Saturn was not its long-term future and began shifting major projects toward its next console, the Dreamcast. Sega also pursued entertainment venue projects during the period, including GameWorks and Sega World locations.
Dreamcast and continuing struggles

Sega launched the Dreamcast in Japan in 1998 and in North America in 1999. The console used more accessible hardware than the Saturn and included a modem for online play, making it one of the first home consoles designed around internet connectivity. Dreamcast titles such as ChuChu Rocket!, Phantasy Star Online, and Alien Front Online helped demonstrate online console gaming, while Sonic Adventure became the first fully 3D mainline Sonic game and one of the system’s best-selling titles.
The Dreamcast struggled at launch in Japan because of limited software and the looming arrival of Sony’s PlayStation 2. Its Western launch was more successful, supported by a stronger lineup and aggressive marketing, with 500,000 consoles sold in its first week in North America.[36]http://www.vidgame.net/SEGA/DC.html The system became known for innovative and critically acclaimed games, including Jet Set Radio, Seaman, Samba de Amigo, Shenmue, Crazy Taxi, and Skies of Arcadia.
Despite its strong software reputation, Dreamcast sales slowed after the PlayStation 2 launch. Sega’s financial difficulties, combined with competition from Sony, Nintendo, and Microsoft, led the company to discontinue the Dreamcast and leave the console hardware market. On January 31, 2001, Sega announced that it would stop producing the Dreamcast after March 31 and restructure as a third-party developer and publisher. The final Sega-published Dreamcast game was NHL 2K2.
Shift to third-party software development


CSK chairman Isao Okawa replaced Shoichiro Irimajiri as Sega president on May 22, 2000. Okawa had long supported the idea of Sega leaving the console business, a view also shared by figures such as David Rosen and former Sega of America executive Bernie Stolar.[37]Kent 2001 p. 581–582[12]IGN Presents the History of SEGA.

On January 23, 2001, Nihon Keizai Shimbun reported that Sega would stop producing the Dreamcast and begin developing software for other platforms. Sega initially denied the report, but later confirmed it was considering software for the PlayStation 2 and Game Boy Advance under a new management policy.[39]. Sega Sinks Console Efforts?. IGN. .

Archived version On January 31, the company confirmed its transition into a “platform-agnostic” third-party developer and publisher.[41]. Sega announces drastic restructuring. GameSpot. . Archived version
Sega began publishing games on former rival platforms, with early examples including ChuChu Rocket! for the Game Boy Advance, Sonic Adventure 2: Battle for the Nintendo GameCube, and Virtua Fighter 4 for the PlayStation 2. The company continued producing arcade hardware during this period, including the Sega NAOMI, Sega NAOMI 2, Sega Hikaru, Sega Chihiro, Triforce, and Sega Lindbergh arcade systems.
Sega’s early third-party period included successful releases, but the company continued to face financial pressure. After Okawa’s death in 2001, CSK sought buyers for Sega. Discussions took place with companies including Sammy, Namco, Bandai, Electronic Arts, and Microsoft. Sega’s Australian operations were also affected during this transition, with Sega Ozisoft changing hands before Sega later re-established an Australian presence through Sega Europe.
Sammy takeover and business expansion

In August 2003, Sammy Corporation purchased 22.4 percent of Sega’s shares from CSK, becoming Sega’s largest shareholder.[42]Sammy merging with Sega. GameSpot. . Archived version[43]. Sammy merging with Sega. GameSpot. . Archived version Sammy chairman Hajime Satomi became CEO of Sega and indicated that the company would focus more heavily on its profitable arcade business. In December 2003, Sega released Sonic Heroes, the first Sonic game to launch across Nintendo GameCube, PlayStation 2, and Xbox.
In 2004, Sammy acquired a controlling share in Sega for $1.1 billion, creating Sega Sammy Holdings. Sega and Sammy became subsidiaries of the new holding company while operating independently under a merged executive structure. The merger led to internal restructuring, including the reabsorption of several second-party studios and changes in corporate culture.[44]. Tetsuya Mizuguchi Interview 2005.
In 2005, Mike Hayes became head of Sega Europe and helped guide the company’s transition as a third-party publisher. That same year, Sega sold Visual Concepts and its subsidiary Kush Games to Take-Two Interactive. Visual Concepts had been responsible for many Sega Sports titles, including the NFL 2K series, and the acquisition helped lead to Take-Two’s 2K Games publishing label.
By the end of 2005, Sega saw stronger earnings across several divisions, supported by pachinko sales and software such as Yakuza, Mushiking, and Sonic the Hedgehog (2006).[45]Notice of Adjustment to the Forecasts of Whole-Year Operating Results for the Year Ending March 31, 2006.

Sega also acquired Relic Entertainment in 2013, strengthening its Western PC strategy alongside existing subsidiaries such as Creative Assembly and Sports Interactive.
Sega Games and Sega Interactive
In April 2015, Sega Corporation was reorganized as part of Sega Group, one of the three groups of Sega Sammy Holdings.

Business interests[edit]
Amusement machines

Sega has been active in the amusement industry for most of its history. Alongside companies such as Namco and Taito, it became one of the major forces in the Japanese arcade market during the second half of the twentieth century. Although the arcade business declined from its peak in the 1980s and early 1990s, Sega remained a prolific manufacturer of arcade and amusement machines, particularly in Japan.
Sega’s amusement machine business has often focused on experiences that are difficult to reproduce in the home. This approach can be seen in arcade titles ranging from Hang-On in 1985 to later music and rhythm games such as Maimai. In Japan, Sega also emphasized networked arcade features, allowing players to compete across different venues and track their progress through mobile apps or physical player cards.
The company’s early business was built around gambling and coin-operated machines. Because real-money gaming is heavily regulated, Sega shifted from the mid-1980s toward “medal” games. These machines use venue-specific currency with no value outside the location, while still offering risk-and-reward mechanics similar to gambling machines.
Although arcades declined sharply in Western markets after the 1980s, Sega continued operating amusement-related businesses in North America and Europe. These branches have distributed products from third-party manufacturers and maintained older Sega arcade machines, particularly racing and shooting games. Titles such as Daytona USA and Sega Rally Championship remained common sights in arcades long after their original release, while Sega’s Western operations also continued supporting new arcade projects for those markets.
Sega has also expanded beyond traditional arcade video games into other amusement products, including change machines, motion simulators, and ride-on machines for young children. Since 1985, the company has produced the UFO Catcher line of crane machines, which became a long-running fixture of Japanese game centers. Sega not only manufactures the cabinets but also sources and distributes prizes for the machines.
Video games



Sega entered the home consumer video game market in 1983 and spent nearly two decades as both a software developer and hardware manufacturer. During that period, the company produced consoles such as the SG-1000, Sega Master System, Sega Mega Drive, Sega Saturn, and Dreamcast. It also created several major game franchises, most notably Sonic the Hedgehog, whose lead character became Sega’s mascot.
After leaving the console hardware business, Sega continued supporting home video game platforms from Nintendo, Sony, and Microsoft, while also expanding its presence on PC and mobile devices. The company had earlier entered the PC market through operations such as SegaSoft and Sega PC, while its later PC strategy became closely tied to Western subsidiaries such as The Creative Assembly, Sports Interactive, and Relic Entertainment. Sega began mobile phone development in 2000 through Sonic Cafe, and mobile gaming later became a significant part of the company’s business. Titles such as Chain Chronicle and Puyo Puyo!! Quest became among its stronger mobile performers.[58]AnnualReport2016 English.pdf. p. 43
Sega maintains internal development studios in Japan, with resources often shared between consumer and arcade projects. Sega of America and Sega Europe also form part of the company’s wider development and publishing structure, though their work has generally centered on external developers, partnerships, and subsidiaries rather than the same internal studio model used in Japan.
Following Sega Sammy’s acquisition of Index Holdings in 2013, Atlus became part of the Sega Sammy group, bringing franchises such as Persona, Megami Tensei, and Etrian Odyssey under the company’s wider structure. Sega’s major active franchises include Sonic the Hedgehog, Phantasy Star Online, Yakuza (Ryu ga Gotoku), Hatsune Miku: Project DIVA, and Puyo Puyo‘.
Entertainment venues
Sega has operated and been affiliated with a wide range of entertainment venues. Its Japanese game centers began opening in the late 1960s, and the company later expanded into locations such as Joypolis indoor amusement parks, Sega World amusement centers, Club Sega arcades, and spa and leisure facilities. At its peak in 1999, Sega operated around 870 venues across Japan.[59]AnnualReport1999 English.pdf. p. 14
Outside Japan, Sega owned and operated venues such as Sega Republic in the United Arab Emirates, as well as locations in Taiwan and China. Financial pressure, the merger with Sammy, and restructuring in the mid-2000s led Sega to part with many of its overseas entertainment venues, including the GameWorks chain in the United States, Sega World venues in Australia and South Korea, and European arcade locations such as SegaWorld London. Some venues continued using the Sega name after Sega no longer directly managed them, particularly following the sales of CA Sega Joypolis and Sega Entertainment.
These dedicated venues gave Sega a place to develop and showcase larger amusement projects, including indoor rides, theater-style attractions, and location tests for new arcade machines.
Consumer products
Sega has also entered the toy, electronics, and broader consumer product markets at various points in its history. One of its most significant moves was the 1994 takeover of Yonezawa Toys, which led to the creation of Sega Toys in 1998. As one of Japan’s largest post-war toy manufacturers, Yonezawa gave Sega a major presence in the Japanese toy industry and helped connect the company with partners such as Hasbro in the United States. Sega Toys continues to exist as a separate entity within Sega Sammy Holdings.
The company has produced and sold a variety of non-game products, including karaoke equipment such as Prologue 21, the Digio SJ-1 digital camera, the Sega-Vision television, IR 7000 Communicator PDAs, and films on VHS. Sega has also worked with partners such as TMS Entertainment on animated productions, while its properties have been adapted into books, albums, board games, audiobooks, and other licensed products.
Sega franchises have also been adapted for the stage. These include biannual theater productions based on Sakura Taisen and later productions such as Phantasy Star Online 2: On Stage.

Research and development
See also: Sega development studios

Sega releases games developed by its internal research and development teams as well as by acquired studios and external partners. The Sonic the Hedgehog franchise is maintained through Sonic Team, one of Sega’s best-known development divisions, and remains one of the company’s central global properties.[73]Sega Sammy Holdings – Annual Report 2014. Sega Sammy Holdings. . pp. 34, 58, 62, 65. Archived version Sega’s development network also includes Atlus, Creative Assembly, Sports Interactive, Sega Hardlight, Two Point Studios, and Rovio Entertainment, among others.
Sega’s internal software development structure began with a single development division under longtime head of research and development Hisashi Suzuki. As the home console market grew, Sega expanded its consumer development work into multiple Consumer Development divisions. Arcade development also expanded into separate development teams, including Sega DD No. 1, 2, and 3, before being reorganized as Sega Amusement Machine Research and Development teams. These became known as the AM teams, and Sega’s arcade and consumer divisions sometimes operated with distinct internal cultures and rivalries.[74]Horowitz 2018, p. 153
In 2000, Sega reorganized its arcade and console development groups into ten semi-autonomous studios led by major Sega designers.[12]IGN Presents the History of SEGA. IGN. . Archived version[75]. 9.9.99, A Dreamcast Memorial. 1Up.com. . Archived version[76]Kent 2001 pp. 577–578, 581 These studios included United Game Artists, Smilebit, Hitmaker, Sega Rosso, WOW Entertainment, Overworks, Wave Master, Amusement Vision, Sega-AM2, and Sonic Team.[77]. IGN Presents the History of Dreamcast. IGN. . Archived version[78]Sega's new beginning. Edge. . Issue 89. pp. 68–78 The structure gave Sega’s creative teams a high level of autonomy during the Dreamcast and early third-party period.
After Sega moved further into third-party development, the company began reintegrating many of those studios into the main company. In 2003, president Hisao Oguchi announced plans to consolidate Sega’s studios, and the reintegration process began before Sammy acquired Sega.[79]. Sega reports a profit, but top execs step down.

Sega’s first-party studios now operate as departments or brands within its research and development structure. Sonic Team functions as Sega’s CS2 research and development department,[82].

Owners
Sega’s ownership structure has changed several times since the company’s early arcade period.
- Gulf and Western Industries owned Sega from 1969 to 1984.
- CSK Corporation became Sega’s largest shareholder after the 1984 management buyout and remained its main owner until the Sega Sammy merger.
- Sega Sammy Holdings has owned Sega since 2004, when Sega and Sammy Corporation became subsidiaries of the newly formed holding company.
Company policy and characteristics[edit]
Community involvement

Sega has maintained a visible relationship with its fan communities, particularly around the Sonic the Hedgehog franchise. The company has often shown tolerance toward fan-created works, including fan art, animations, music, mods, ROM hacks, and fangames, and has occasionally promoted or acknowledged fan projects through official channels.
Several creators from Sega fan communities have later worked with the company. Christian “Taxman” Whitehead, known for his work on Sonic fangames and ROM hacks, was hired by Sega in 2009 to develop updated versions of Sonic the Hedgehog, Sonic the Hedgehog 2, and Sonic the Hedgehog CD. Sega later worked with other developers, ROM hackers, artists, and musicians from the fan community on Sonic Mania, which became one of the most notable examples of official collaboration between Sega and long-time Sonic fan creators.
Sega has also recognized fan sites and communities connected to its games. Fan outlets such as SEGAbits, Sega-16, The Sonic Stadium, TSSZ News, and Mega Visions have received official Sega Seals of Quality. The company has also provided community contact channels for fan communities and creators to share work related to Sega properties.
On 17 May 2019, Sega and Hardlight publicly expressed support for the LGBTQ+ community.[83]SEGA HARDlight on Twitter. Twitter.
Charity and philanthropy
Sega has supported charitable work through fundraising, sponsorships, awareness campaigns, and partnerships with charity organizations. Its charitable activity has included support for children’s hospitals, Stand Up to Cancer, endangered animal sanctuaries, the Red Cross, Doctors Without Borders, War Child Gaming, and initiatives supporting people with disabilities.
Through Humble Bundle campaigns, Sega has raised more than $2 million for various charities. Its charity work has also been connected to wider industry campaigns that encourage game developers and publishers to support humanitarian, medical, educational, and accessibility-related causes.
