Blizzard Entertainment was founded by
Michael Morhaime, Allen Adham, and Frank Pearce as Silicon & Synapse in February 1991, after all three had earned their
bachelor's degree

The name "Silicon & Synapse" was a high concept from the three founders, with "silicon" representing the building block of a computer, while "synapse" the building block of the brain.
The initial logo was created by Stu Rose.
To fund the company, each of them contributed about $10,000, Morhaime borrowing the sum interest-free from his grandmother. Their offices were established in a business park near the

Brian Fargo was friends with Adham and had a 10% stake in Silicon & Synapse. Fargo provided the company with conversion contacts for the games Interplay was publishing, starting with ''
Battle Chess''.
[Schreier, 2024, Chapter 1] Other titles included Ports include titles such as ''
J.R.R. Tolkien's The Lord of the Rings, Vol. I'' and ''Battle Chess II: Chinese Chess''.
Fargo then enlisted Silicon & Synapse around 1991 to help develop ''

Rock n' Roll Racing'', a sequel to ''RPM Racing'', and ''
The Lost Vikings'' inspired by ''
Lemmings''.
Around 1993, co-founder Adham told the other executives that he did not like the name "Silicon & Synapse" anymore, as outsiders were confusing the

Westwood Studios' ''

'', the company began work on what would become ''
Warcraft: Orcs & Humans''. Adham saw this as a start of a series of interconnected titles, similar to the ''
Gold Box'' series by ''
Strategic Simulations''. To support its development and keep the company afloat, the studio took several more conversion contracts, though the founders were going into debt to keep their twelve developers employed.
Davidson & Associates, a company that published educational software and which had previously employed Silicon & Synapse for conversion contracts, made an offer to buy the company for $4 million. Interplay was negotiating to be the publisher for ''Warcraft'', and Fargo cautioned Adham and Morhaime against selling the company. Adham and Morhiame rejected Davidson & Associates' initial offer, but the company came back with another offer of $6.75 million (equivalent to $ million in ), assuring to the founders that they would have creative control over the games they developed.
[Schreier, 2024, Chapter 2] Adham and Morhaime accepted the offer in early 1994.
Shortly after the sale, they were contacted by a Florida company, Chaos Technologies, who claims their trademark rights on the name "Chaos" and wanted the company to pay () to keep the name. Not wanting to pay that sum, the executives decided to change the studio's name to "Ogre Studios" by April 1994.
However, Davidson & Associates did not like this name, and forced the company to change it. According to Morhaime, Adham began running through a dictionary from the start, writing down any word that seemed interesting and passing it to the legal department to see if it had any complications. One of the first words they found to be interesting and cleared the legal check was "blizzard", leading them to change their name to "Blizzard Entertainment" by May 1994.
''Warcraft'' was released in November 1994, and within a year, helped to establish Blizzard among other development studios like Westwood.
Acquisition by Vivendi and ''World of Warcraft'' (1995–2007)
Blizzard Entertainment has changed hands several times since then. Davidson was acquired along with
Sierra On-Line by a company called
CUC International in 1996. CUC then merged with a hotel, real-estate, and car-rental franchiser called
HFS Corporation to form
Cendant in 1997. In 1998 it became apparent that CUC had engaged in accounting fraud for years before the merger. Cendant's stock lost 80% of its value over the next six months in the ensuing widely discussed accounting scandal. The company sold its consumer software operations, Sierra On-line (which included Blizzard) to French publisher

''Diablo'' was released at the very start of 1997 alongside
Battle.net, a matchmaking service for the game. Blizzard North developed the sequel ''

Lord of Destruction'' (2001).
Following the success of ''
Warcraft II: Tides of Darkness'', Blizzard began development on a science fiction-themed RTS, ''
StarCraft'', and released the title in March 1998. The title was the top-selling PC game for the year,
and led to further growth of the Battle.net service and the use of the game for

Around 2000, Blizzard engaged with
Nihilistic Software to work on a version of ''StarCraft'' for home consoles for Blizzard. Nihilisitic was co-founded by Robert Huebner, who had worked on ''StarCraft'' and other games while a Blizzard employee before leaving to found the studio. The game, ''
StarCraft: Ghost'', was a
stealth-oriented game compared to the RTS features of ''StarCraft'', and was a major feature of the 2002

. However, over the next few years, the game entered
development hell with conflicts between Nihilisitic and Blizzard on its direction. Blizzard ordered Nihilistic to stop work on ''StarCraft: Ghost'' in July 2004, and instead brought on Swingin' Ape Studios, a third-party studio that had just successfully released ''
Metal Arms: Glitch in the System'' in 2003, to reboot the development of ''Ghost''.
Blizzard fully acquired Swingin' Ape Studios in May 2005 to continue on ''Ghost''. However, while the game was scheduled to be released in 2005, it was targeted at the consoles of the
sixth generation, such as the

Blizzard started to work on a sequel to the ''Warcraft II'' in early 1998, which was announced as a "role-playing strategy" game.

Around 2003, Blizzard North was working on ''
Diablo III'' as well as planned science-fiction-based version dubbed ''Starblo''. Amid rumors that Vivendi was looking to sell its gaming division around 2003, Blizzard North's leadership, consisting of Brevik, the Schaefers, and
Bill Roper, asked Blizzard to provide their studio protections from the potential sale, or else they would resign. After several rounds of tense communications, the four gave their resignations to Blizzard's management on June 30, 2003. As part of this, a significant portion of Blizzard North's staff were laid off, additional work on ''Starblo'' was terminated and the remaining team focused ''Diablo III''.
[Schreier, 2024, Chapter 6: Resignations Accepted] Blizzard's management made the decision August 2005 to
consolidate Blizzard North into Blizzard Entertainment, relocating staff to the main Blizzard offices in Irvine.
In 2004, Blizzard opened European offices in the Paris suburb of
Vélizy, Yvelines, France.
Blizzard began work on ''

(MMORPG) based on the ''Warcraft'' franchise, with gameplay inspired by ''
EverQuest''. The game was publicly announced in September 2001.
The excitement by the media for ''World of Warcraft'' led to significant growth with Team 2 from forty to the hundreds, as well as a large amount of crunch development to complete the game. In January 2004, Adham announced he was leaving the company from being burnt out over his work on ''World of Warcraft'', transferring management to Morhaime.
''World of Warcraft'' was released on November 23, 2004, in North America, and on February 11, 2005, in Europe. By December 2004, the game was the fastest-selling PC game in the United States, and by March 2005, had reached 1.5 million subscribers worldwide.
Blizzard partnered with Chinese publisher
The9
The9 (stylized as THE9 or THE NINE) was a Chinese girl group formed through the IQIYI survival show Youth With You (season 2), ''Youth With You 2''. The group consisted of Liu Yuxin (singer), Liu Yuxin, Yu Shuxin, Xu Jiaqi, Yu Yan (singer), Yu ...
to publish and distribute ''World of Warcraft'' in China, as foreign companies could not directly publish into the country themselves. ''World of Warcraft'' launched in China in June 2005. By the end of 2007, ''World of Warcraft'' was considered a global phenomenon, having reached over 9 million subscribers
and exceeded in revenue since its release.
In April 2008, ''World of Warcraft'' was estimated to hold 62 percent of the MMORPG subscription market.
With the success of ''World of Warcraft'', Blizzard Entertainment organized the first
BlizzCon fan convention in October 2005 held at the
Anaheim Convention Center. The inaugural event drew about 6,000 people and became an annual event which Blizzard uses to announce new games, expansions, and content for its properties.
Blizzard's staff quadrupled from around 400 employees in 2004 to 1600 by 2006 to provide more resources to ''World of Warcraft'' and its various expansions.
To deal with its growing staff, Blizzard moved their headquarters from the
UCI Research Park campus to a newly constructed 240,000-square foot campus in Irvine that was formerly occupied by

Jean-Bernard Lévy about potential acquisition of their struggling Vivendi Games division, which included Blizzard Entertainment. Lévy was open to a merger, but would only allow it if he controlled the majority of the combined company, knowing the value of ''World of Warcraft'' to Kotick.
Among those Kotick spoke to for advice included Blizzard's Morhaime, who told Kotick that they had begun establishing lucrative in-roads into the
Chinese market. Kotick accepted Lévy's deal, with the deal approved by shareholders in December 2007. By July 2008, the merger was complete, with Vivendi Games effectively dissolved except for Blizzard Entertainment, and the new company was named

They released an improved version of
Battle.net (Battle.net 2.0) in March 2009 which included improved matchmaking, storefront features, and better support for all of Blizzard's existing titles particularly ''World of Warcraft''.
Having peaked at 12 million monthly subscriptions in 2010, ''World of Warcraft'' subscriptions sunk to 6.8 million in 2014, the lowest number since the end of 2006, prior to ''

Mike Morhaime accepted the award.
Following the merger, Blizzard found it was relying on its well-established properties, but at the same time, the industry was experiencing a shift towards
indie games. Blizzard established a few small teams within the company to work on developing new concepts based on the indie development approach that it could potentially use. One of these teams quickly came onto the idea of a
collectible card game

based on the ''Warcraft'' narrative universe, which ultimately became ''
Hearthstone'', released as a free-to-play title in March 2014.
''Hearthstone'' reached over 25 million players by the end of 2014, and exceeded 100 million players by 2018.
Another small internal team began work around 2008 on a new intellectual property known as ''
Titan'', a more contemporary or near-future MMORPG that would have co-existed alongside ''World of Warcraft''. The project gained more visibility in 2010 as a result of some information leaks. Blizzard continued to speak on ''Titan''s development over the next few years, with over 100 people within Blizzard working on the project. However, ''Titan''s development was troubled, and, internally, in May 2013, Blizzard cancelled the project (publicly reporting this in 2014), and reassigned most of the staff but left about 40 people, led by
Jeff Kaplan, to either come up with a fresh idea within a few weeks or have their team reassigned to Blizzard's other departments. The small team came upon the idea of a team-based multiplayer shooter game, reusing many of the assets from ''Titan'' but set in a new near-future narrative. The new project was greenlit by Blizzard and became known as ''
Overwatch'', which was released in May 2016. ''Overwatch'' became the fourth main intellectual property of Blizzard, following ''Warcraft'', ''StarCraft'', and ''Diablo''.
In addition to ''Hearthstone'' and ''Overwatch'', Blizzard Entertainment continued to produce sequels and expansions to its established properties during this period, including ''
StarCraft II: Wings of Liberty'' (2010) and ''
Diablo III'' (2012). Their
major crossover title, ''
Heroes of the Storm'', was released as a
MOBA game in 2015.
The game featured various characters from Blizzard's franchises as playable heroes, as well as different battlegrounds based on ''Warcraft'', ''Diablo'', ''StarCraft'', and ''Overwatch'' universes. In the late 2010s, Blizzard released ''
StarCraft: Remastered'' (2017) and ''

remastered versions of the original ''StarCraft'' and ''Warcraft III,'' respectively''.''

Change of leadership (2018–2022)
By 2018, a rift had developed between Kotick and Morhaime on how Blizzard should continue developing its games, with Morhaime wanting to allow the developers the freedom to experiment while Kotick was focused on generating profit. Morhaime had considered resigning in 2017 but Kotick convinced him to stay on. Morhaime announced his plans to step down as the company president and CEO On October 3, 2018, while remaining an advisor to the company. Morhaime stated publicly that he felt it was time for someone else to lead Blizzard, but those close to him said he had become tired of the conflicts with Kotick.
[Schreier, 2024, Chapter 24: Changing of the Guard] Morhaime formally left on April 7, 2019, and was replaced by J. Allen Brack, the executive producer on ''World of Warcraft''.
In February 2019, Kotick announced a company-wide layoff of 8% of Activision Blizzard staff, around 800 total positions, due to lower revenues in 2018; this included a significant portion of Blizzard Entertainment, which had been since as having bloated head count over the years.
[Schreier, 2024, Chapter 25: Cost Reduction] Blizzard was planning for the announcement of ''Diablo IV'' and ''Overwatch 2'' at the 2019 Blizzcon, and to keep the company focused, two other projects, codenamed ''Ares'' and ''Orion'', were cancelled.
Frank Pearce announced he would be stepping down as Blizzard's Chief Development Officer on July 19, 2019, though will remain in an advisory role similar to Morhaime. Michael Chu, lead writer on many of Blizzard's franchises including ''Diablo'', ''Warcraft'', and ''Overwatch'', announced he was leaving the company after 20 years in March 2020.
On January 22, 2021, Activision transferred
Vicarious Visions
Blizzard Albany (formerly Vicarious Visions, Inc.) is an American video game development division of Blizzard Entertainment based in Albany, New York. Founded in 1991, the company was acquired by Activision in January 2005. In January 2021, Vica ...
over to Blizzard Entertainment, stating that the Vicarious Visions team had better opportunity for long-term support for Blizzard. Vicarious had been working with Blizzard for about two years prior to this announcement on the planned
remaster of ''
Diablo II'', ''
Diablo II: Resurrected'', and according to Brack, it made sense to incorporate Vicarious into Blizzard for ongoing support of the game and for other ''Diablo'' games including ''
Diablo IV''. Vicarious was completely merged into Blizzard by April 12, 2022, thereby being renamed Blizzard Albany.
In celebration of the company's 30th anniversary, Blizzard Entertainment released a compilation called ''Blizzard Arcade Collection'' in February 2021, for various video game platforms. The collection includes their three classic video games: ''
The Lost Vikings'', ''
Rock n' Roll Racing,'' and ''
Blackthorne,'' each of which containing additional upgrades and numerous modern features.
Activision Blizzard was the subject of
a lawsuit from the
California Department of Fair Employment and Housing in July 2021, asserting that for several years the management within Blizzard as well as Activision promoted a "frat boy" atmosphere that allowed and encouraged sexual misconduct towards female employees and discrimination in hiring practices.
The lawsuit drew a large response from employees and groups outside of Activision Blizzard. In the wake of these events, Brack, one of the few individuals directly named in the suit, announced he was leaving Blizzard to "pursue new opportunities", and will be replaced by co-leads Jen Oneal, the lead of Vicarious Visions and the first woman in a leadership role for the company, and Mike Ybarra, a Blizzard executive vice president. Oneal announced in November 2021 that she would be leaving the company by the end of 2021, leaving Ybarra as the sole leader of Blizzard.
As a result of the California lawsuit and of delays and release issues with their more recent games, Activision Blizzard's stock faced severe pressure. Subsequently,

Challenges with NetEase and Microsoft acquisition (2022–present)
Ahead of their license renewal in January 2023, Blizzard (via Activision Blizzard) and NetEase stated in November 2022 that they had been unable to come to an agreement on the renewal terms for their license, and thus most Blizzard games will cease operations in China in January 2023 until the situation can be resolved. According to a report by ''

'', several factors influenced Activision Blizzard's decision to terminate the agreement, which included stronger demands made by the Chinese government to know of Activision Blizzard's internal business matters, NetEase's desire to license the games directly rather than run the license through a joint venture, and Activision Blizzard's concerns that NetEase was trying to start their own ventures, including the payment towards Bungie in 2018. NetEase was further concerned about the impact of the pending acquisition of Activision Blizzard by

. Activision Blizzard stated they were looking to other Chinese firms as replacements for NetEase as to restore their games in China. By April 2024, Blizzard, with Microsoft's help, and NetEase had agreed to new publishing terms, with plans to bring back Blizzard's games to China by mid-2024, maintaining all prior game ownership from the original publishing deal. Under this new deal, NetEase also will be able to bring games to the Xbox platform.
Following completion of the acquisition, Microsoft announced it was laying off 1,900 staff from
Microsoft Gaming on January 25, 2024. Alongside this, Blizzard President Mike Ybarra and Chief Design Officer Allen Adham announced they would be leaving the company. Further, the planned survival game from Blizzard was canceled.

Games
Blizzard Entertainment has developed 19 games since the inception of the company in 1991.
Main franchises
The majority of the games Blizzard published are in the ''
Warcraft'', ''
Diablo'', and ''
StarCraft'' series. Since the release of ''
Warcraft: Orcs & Humans'' (1994), ''
Diablo'' (1997), and ''
StarCraft'' (1998), the focus has been almost exclusively on those three franchises. ''
Overwatch'' (2016) became an exception years later, bringing the number of main franchises to four. Each franchise is supported by other media based around its intellectual property such as novels, collectible card games, comics and video shorts. Blizzard announced in 2006 that they would be producing a
''Warcraft'' live-action film. The movie was directed by

Spin-offs
Blizzard has released two
spin-offs to the main franchises: ''
Hearthstone'' (2014), which is set in the existing ''Warcraft'' lore, and ''
Heroes of the Storm'' (2015), which features playable characters from all four of Blizzard's franchises.
Remasters
In 2015, Blizzard Entertainment formed "Classic Games division", a team focused on updating and
remastering some of their older titles, with an initially announced focus on ''
StarCraft: Remastered'' (2017), ''
Warcraft III: Reforged'' (2020)'','' and ''
Diablo II: Resurrected'' (2021)''.''

Unreleased and future games
Notable unreleased titles include ''
Warcraft Adventures: Lord of the Clans'', an
adventure game which was canceled on May 22, 1998;
[Schreier, 2024, Chapter 5: Fugitives] ''Shattered Nations'', a
turn-based strategy game cancelled around 1996;
[Schreier, 2024, Chapter 4: Warcraft Goes Purple] and ''
StarCraft: Ghost'', an action game aimed for release on consoles, co-developed with
Nihilistic Software, which was "postponed indefinitely" on March 24, 2006, after being in
development hell for much of its lifespan.
[Schreier, 2024, Chapter 11: "That King of Looked Like Me"]
Work on a project called ''Nomad'' started around 1998 after the release of ''Starcraft'', with development led by Duane Stinnett. ''Nomad'' was inspired by the tabletop role playing game ''
Necromunda'' that was played in a
post-apocalyptic setting. The project had vague goals, and around that time, many of the staff of Blizzard began playing
MMORPGs ''
EverQuest'' and ''
Ultima Online''. ''Nomad'' was cancelled in 1999 as Blizzard shifted to making their own MMORPG, ''World of Warcraft''.
[Schreier, 2024, Chapter 8: Nomad]
In the wake of the 2018 layoffs, two projects were cancelled: One was codenamed ''Orion'', an asynchronous card game for mobile devices designed by ''Hearthstone'' developers. While the game was considered fun to play when players were engaged in real time, the asynchronous aspect diluted the enjoyment of the. The second, codenamed ''Ares'', was a first-person shooter within the ''Starcraft'' universe inspired by

After seven years of development, Blizzard revealed the cancellation of an unannounced MMO codenamed ''
Titan'' on September 23, 2014, though ''
Overwatch'' was created from its assets. The company also has a history of declining to set release dates, choosing to instead take as much time as needed, generally saying a given product is "done when it's done."
''Pax Imperia II'' was originally announced as a title to be published by Blizzard. Blizzard eventually dropped ''Pax Imperia II'', though, when it decided it might be in conflict with their other space strategy project, which became known as ''
StarCraft''. THQ eventually contracted with Heliotrope and released the game in 1997 as ''

. When the game was revealed in 2022, about 100 employees were working on it, but around the same time, there was effort to switch from Unreal to Synapse, Blizzard's engine used for mobile games, though artists continued to develop assets in Unreal. Near when Microsoft completed its acquisition of Activision Blizzard, there was an internal belief that they would be able to bring on more developers to complete the transition to Synapse and have the game ready for a 2026 release, but with the culling of 1,900 staff from
Microsoft Gaming in January 2024, the game's development was cancelled.
Ports
The company, known at the time as the Silicon & Synapse, initially concentrated on
porting other studios' games to computer platforms, developing 8 ports between 1992 and 1993.
Company structure
As with most studios with multiple franchises, Blizzard Entertainment has organized different departments to oversee these franchises. Formally, since around the time of ''World of Warcraft'' in 2004, these have been denoted through simply numerical designations.
The original three teams were:
* Team 1 manages the ''StarCraft'' property.
The team also oversaw the development of the ''StarCraft'' spin-off ''
Heroes of the Storm''. Team 1 also included the Classics Team to work on remastering Blizzard's earlier properties for modern computers, which have included ''
StarCraft: Remastered'', ''
Warcraft III: Reforged'' and ''
Diablo II: Resurrected''. The Classic Games team was disbanded around August 2020, about eight months after ''Warcraft III: Reforged'' was released; according to
Jason Schreier of ''

'', this was due to Activision Blizzard driving Blizzard away from remastering its old properties, which figured into the launch issues with ''Warcraft III: Reforged''.
* Team 2 continues to manage and create content for ''World of Warcraft''.
* Team 3 oversees the ''Diablo'' franchise.
Since 2004, two new teams were created:
* Team 4 was created around 2007 to work on Blizzard's first new IP since ''World of Warcraft'', that being ''
Titan''. ''Titan'' had development difficulties near 2013, and most of Team 4 was reallocated to the other teams, but the remaining members, led by Jeff Kaplan, revised ''Titan''s concept into ''
Overwatch'', which remains in Team 4's hands since its release in 2016.
* Team 5 was created in 2008 to explore smaller games that could fit into Blizzard's portfolio. This resulted in the creation of ''
Hearthstone'', a collectible card game based on the ''Warcraft'' property, which became Team 5's priority.
Blizzard has used an informal motto, "it'll be ready when it's ready" to describe the release schedule for its games. The concept of accepting delays in software releases originally came about when the company opted to push back the release of ''Diablo'' to assure a quality product at release. By the time of ''World of Warcraft'', employees began using the phrase in response to eager fans looking for a release date.

Warden client
Blizzard Entertainment has made use of a special form of software known as the 'Warden Client'. The Warden client is known to be used with Blizzard's online games such as ''Diablo'' and ''World of Warcraft'', and the Terms of Service contain a clause consenting to the Warden software's RAM scans while a Blizzard game is running.
The Warden client scans a small portion of the
code segment of running processes in order to determine whether any third-party programs are running. The goal of this is to detect and address players who may be attempting to run unsigned code or third party programs in the game. This determination of third party programs is made by
hashing the scanned
strings and comparing the hashed value to a list of hashes assumed to correspond to banned third party programs. The Warden's reliability in correctly discerning legitimate versus illegitimate actions was called into question when a large-scale incident happened. This incident banned many Linux users after an update to Warden caused it to incorrectly detect
Cedega as a cheat program. Blizzard issued a statement claiming they had correctly identified and restored all accounts and credited them with 20 days' play. Warden scans all processes running on a computer, not just the game, and could possibly run across what would be considered private information and other
personally identifiable information. It is because of these peripheral scans that Warden has been accused of being

''California Department of Fair Employment and Housing v. Activision Blizzard''
Following a two-year investigation, the
California Department of Fair Employment and Housing (DFEH) filed a lawsuit against Activision Blizzard in July 2021 for gender-based discrimination and sexual harassment, principally within the Blizzard Entertainment workplace. The DFEH alleges that female employees were subjected to constant sexual harassment, unequal pay, retaliation, as well as discrimination based on pregnancy. The suit also described a "pervasive frat boy workplace culture" at Blizzard that included objectification of women's bodies and jokes about rape.
Activision Blizzard's statement described the suit as meritless, contending that action had been taken in any instances of misconduct. The company also objected to the DFEH not approaching them prior to filing. The lawsuit prompted an employee walkout, as well as leading J Allen Brack, and head of human resources, Jesse Meschuk, to step down.
Amidst the lawsuit, Morhaime, Brack's predecessor, posted a statement to Twitter writing that he was “ashamed.” Because of these allegations, Blizzard changed names that referenced employees in multiple of its franchises, including ''Overwatch'' and ''World of Warcraft''.

, one player Ng Wai Chung, going by his online alias "Blitzchung" used an interview period to show support for the protestors in the
2019–20 Hong Kong protests. Shortly afterwards, on October 7, 2019, Blitzchung was disqualified from the current tournament and forfeited his winnings to date, and banned for a one-year period. The two shoutcasters engaged in the interview were also penalized with similar bans. Blizzard justified the ban as from its ''Grandmasters'' tournament rules that prevents players from anything that "brings
hemselvesinto public disrepute, offends a portion or group of the public, or otherwise damages
lizzard'simage".
Blizzard's response led to several protests from current ''Hearthstone'' players, other video game players, and criticism from Blizzard's employees, fearing that Blizzard was giving into the censorship of the Chinese government. Protests were held, including through the 2019
BlizzCon in early November, to urge Blizzard to reverse their bans. The situation also drew the attention of several U.S. lawmakers, fearing that Blizzard, as a U.S. company, was letting China dictate how it handled speech and also urged the bans to be reversed.
Blizzard CEO J. Allen Brack wrote an open letter on October 11, 2019, apologizing for the way Blizzard handled the situation, and reduced the bans for both Blitzchung and the casters to six months. Brack reiterated that while they support free speech and their decision was in no way tied to the Chinese government, they want players and casters to avoid speaking beyond the tournament and the games in such interviews.
King's "Diversity Tool" controversy
On May 12, 2022, Blizzard Entertainment released a blog post about the Diversity Space Tool, developed by a team at
King
King is a royal title given to a male monarch. A king is an Absolute monarchy, absolute monarch if he holds unrestricted Government, governmental power or exercises full sovereignty over a nation. Conversely, he is a Constitutional monarchy, ...
– a mobile business unit at Activision Blizzard – alongside the
MIT Game Lab. Jacqueline Chomatas, King's globalization project manager, described the tool as a "measurement device" to analyze how diverse the characters are "when compared to the 'norm'". The post showed example images of the tool being used on ''Overwatchs cast, with graphs showing breakdowns of the character attributes, and stated that "The Overwatch 2 team at Blizzard has also had a chance to experiment with the tool, with equally enthusiastic first impressions." Blizzard shared the intent to release the tool during the summer and fall of 2022, with the goal of "making the tool available to the industry as a whole".
The tool received heavy backlash online. Many people asked why Blizzard would create the tool instead of hiring diverse teams, and raised questions regarding the tool's rating scale.
The blog post originally suggested that the tool was used in an active development, mainly for ''Overwatch'', which led some Blizzard employees working on the game to publicly deny the tool was used in ''Overwatch'' development and to criticize the tool further.
On May 13, 2022, the blog post was edited to remove the example images of the tool and any mention of ''Overwatch''.
Later, the post was deleted altogether.

''MDY v. Blizzard''s decision did affirm a prior Ninth Circuit ruling in ''
Vernor v. Autodesk, Inc.'' that software licenses, such as the one used by Blizzard for ''WoW'', were enforceable and enshrined the principle that video games could be sold as licenses to players rather than purchased. This ruling, though limited to the states of the Ninth Circuit, has been used by the industry to continue to sell games as licenses to users.
Privacy controversy and Real ID
On July 6, 2010, Blizzard Entertainment announced that they were changing the way their forums worked to require that users identify themselves with their real name. The reaction from the community was overwhelmingly negative with multiple game magazines calling the change "foolhardy" and an "epic fail". It resulted in a significant user response on the Blizzard forums, including one thread on the issue reaching over 11,000 replies.
This included personal details of a Blizzard employee who gave his real name "to show it wasn't a big deal". Shortly after revealing his real name, forum users posted personal information including his phone number, picture, age, home address, family members, and favorite
TV shows and
films

.
Some technology media outlets suggested that displaying real names through Real ID is a good idea and would benefit both Battle.net and the Blizzard community. But others were worried that Blizzard was opening their fans up to real-life dangers such as stalking, harassment, and employment issues, since a simple Internet search by someone's employer can reveal their online activities.
Blizzard initially responded to some of the concerns by saying that the changes would not be retroactive to previous posts, that parents could set up the system so that minors cannot post, and that posting to the forums is optional.
However, due to the significant negative response, Blizzard President
Michael Morhaime issued a statement rescinding the plan to use real names on Blizzard's forums for the time being. The idea behind this plan was to allow players who had a relationship outside of the games to find each other more easily across all the Blizzard game titles.
''StarCraft'' privacy and other lawsuits
In 1998, Donald P. Driscoll, an
Albany, California attorney, filed a suit on behalf of Intervention, Inc., a California consumer group, against Blizzard Entertainment for "unlawful business practices" for the action of collecting data from a user's computer without their permission.
On May 19, 2014, Blizzard Entertainment filed a lawsuit in federal court in California, alleging that the unidentified programmers were involved in creation of software that hacks ''StarCraft II''. Most of the alleged charges are related to copyright infringement.
Back in May 2010, MBCPlus Media, which operates the network MBCGame (Korean television stations that are broadcasting tournaments built around ''StarCraft''), was sued by Blizzard for broadcasting StarCraft tournaments without the company's consent, insisting that ''StarCraft'' is not a public domain offering, as Blizzard has invested significant money and resources to create the ''StarCraft'' game.

Related companies
Over the years, some former Blizzard Entertainment employees have moved on and established gaming companies of their own. Several of these occurred following the merger between Activision Holdings and Blizzard's parent company at the time,
Vivendi Games in 2008, and more recently as Activision Blizzard has directed Blizzard away from properties like ''Warcraft'' and ''StarCraft'' that are not seen as financial boons to the larger company. These employees left to form their smaller studios to give themselves the creative freedom that they were lacking at Blizzard. Collectively these studios are known as "Blizzard 2.0".
