Blizzard Entertainment is a North American video game developer and distributor located in Irvine, California. The company was founded in 1991 under the name Silicon & Synapse by Allen Adham, Michael Morhaime, and Frank Pierce. The original vision of the company was to create ports of games developed by other companies before they started developing their own in 1993. The name changed to Chaos Studios and then to Blizzard Entertainment in 1994.
Shortly after renaming, Blizzard released Warcraft: Orks and Humans, and continued to produce games such as the Diablo and StarCraft series. In 2004, it released the massively popular World of Warcraft role playing game, based on the Warcraft series.
StarCraft in particular was one of the precursors of esports as it is today, as it was widely popular and served as the platform on which became the bedrock of professional gaming. South Korea in particular developed its esports scene with StarCraft. In 2016, Blizzard released Overwatch and plans to host a professional league, Overwatch League, in 2017.
