BlizzCon is a Blizzard Entertainment-hosted gaming convention.
The first BlizzCon was held October 28–29, 2005. The Major announcement was the first World of Warcraft expansion pack, The Burning Crusade, as well as the new Horde race, the Blood Elves.
Playable demos of The Burning Crusade and StarCraft: Ghost were also available.
In 2006, Blizzard had neither a BlizzCon nor a Worldwide Invitational, instead they attended the Electronics Entertainment Expo (or E3) and unveiled the new Alliance race for the Burning Crusade expansion pack, the Draenei. This was the last E3 Blizzard attended, and they have since preferred to hold their own events.
The only game that had a playable demo was the Burning Crusade, as StarCraft: Ghost had been "indefinatly postponed" by this time.
On the 12th of April 2007 Blizzard announced that they would be holding a second convention this year. This convention was held on August 3, 2007. Details about the event are limited to what was included in the announcement;
Highlights for this year's BlizzCon included:
- Discussion panels with Blizzard game developers;
- Competitive and casual tournaments, including a World of Warcraft TCG tournament;
- Costume, machinima, and character sound-alike contests with great prizes;
- Live orchestral performances of music from Blizzard games;
- And many more exciting activities.
The major announcement at the convention was the second World of Warcraft expansion pack, The Wrath of the Lich King.
During the convention, the Terran race was revealed, along with aspects of the Terran campaign. A lore discussion and art discussion  were held. Those attending the convention also were able to play skirmished StarCraft II matches, either multiplayer or against a computer, using either the Terran or Protoss races.
On May 12, 2008, Blizzard announced their third Blizzcon event gaming convention, to be held at the Anaheim Convention Center in Anaheim, California on October 10 and 11. In response to the demand to accommodate more attendees, this year's event was expanded from two convention halls to three.
