Blizzard Entertainment is an American video game developer and publisher based in Irvine, California. It is known for long-running game series such as Warcraft, Diablo, StarCraft, Overwatch, and Hearthstone.
The company began in 1991 as Silicon & Synapse. It later used the name Chaos Studios before becoming Blizzard Entertainment in 1994. Blizzard became part of Activision Blizzard after the 2008 merger of Activision and Vivendi Games. In October 2023, Microsoft completed its acquisition of Activision Blizzard King, bringing Blizzard under Microsoft Gaming.
History
Blizzard was founded by Michael Morhaime, Allen Adham, and Frank Pearce. Its early work included console ports and original games such as The Lost Vikings and Rock n' Roll Racing.
The company's profile changed with Warcraft: Orcs & Humans in 1994, followed by Diablo in 1997 and StarCraft in 1998. These games helped establish Blizzard's reputation for PC-focused fantasy, science fiction, and online multiplayer design.
World of Warcraft, released in 2004, became the company's most important live service. It turned the Warcraft setting into a subscription-based online world and shaped Blizzard's business for years.
Main Series
Blizzard's core series include:
- Warcraft, covering strategy games, World of Warcraft, expansions, novels, and related media.
- Diablo, an action role-playing series built around loot, character builds, dungeons, and dark fantasy.
- StarCraft, a science fiction real-time strategy series with a strong competitive history.
- Hearthstone, a digital card game based on the Warcraft setting.
- Overwatch, a team-based hero shooter.
Blizzard has often supported fewer franchises than some other large publishers, but it has tended to support them for long periods through expansions, seasons, balance patches, and online services.
Battle.net and Online Services
Battle.net is Blizzard's online service and launcher. It began as an online service for multiplayer games and later became a central account, store, social, patching, and launcher system for Blizzard titles.
Blizzard's games are closely tied to online accounts, patches, matchmaking, seasonal updates, and live operations. This live-service model gives games a long lifespan, but it also makes balance changes, server stability, monetisation, and community trust recurring issues.
Microsoft Ownership
Microsoft announced plans to acquire Activision Blizzard in January 2022 and completed the acquisition on 13 October 2023. The deal placed Activision, Blizzard, and King within Microsoft's gaming business.
For Blizzard, the acquisition changed corporate ownership but did not remove the studio's existing live games. The longer-term effect depends on staffing, platform strategy, publishing priorities, and how Microsoft handles the inherited franchises.
Workplace and Public Controversies
Blizzard's public image has been affected by several controversies. These include criticism of decisions around esports discipline, reception to some releases and remasters, complaints about live-service monetisation, and serious workplace allegations directed at Activision Blizzard.
In December 2023, the California Civil Rights Department announced a settlement agreement to resolve employment discrimination and equal pay allegations against Activision Blizzard, Blizzard Entertainment, and Activision Publishing. The settlement followed litigation that had already affected the company's leadership, staff relations, and public reputation.
