BlizzCon

BlizzCon is an annual gaming convention held by Blizzard Entertainment to promote its major franchises including Warcraft, StarCraft, Diablo, Hearthstone, Heroes of the Storm, and Overwatch.

The first BlizzCon was held in October 2005, and since then, all of the conventions have been held at the Anaheim Convention Center in Anaheim, California, in the same metropolitan area as Blizzard's headquarters in Irvine. The convention features game-related announcements, previews of upcoming Blizzard Entertainment games and content, Q&A sessions and panels, costume contests, and playable versions of various Blizzard games. The Closing Ceremony has featured concerts by The Offspring, Tenacious D, Foo Fighters, Ozzy Osbourne, Blink-182, Metallica, Linkin Park, "Weird Al" Yankovic, and Muse. Blizzard also hosted a similar event outside the U.S. from 2004 to 2008, the Blizzard Worldwide Invitational.
