FOR IMMEDIATE RELEASE

October 11, 2010

PARIS, France --Blizzard Entertainment, Inc. today announced that the greatest band in the world*, Tenacious D, will perform at the closing concert during this year’s sold-out BlizzCon ^®. Taking place October 22-23 at the Anaheim Convention Center, BlizzCon is a celebration of the global player communities surrounding Blizzard Entertainment’s Warcraft ^®, Diablo ^®, and StarCraft ^® game universes. While tickets to the convention are currently sold out, viewers can watch at home by ordering a BlizzCon Virtual Ticket, offering over 50 hours of event coverage (including Tenacious D’s performance) globally over the Internet and also on DIRECTV ^® in the United States.

Tenacious D is made up of musical visionaries Jack Black and Kyle Gass. After forming in 1994, the duo rose to rock god-dom following the release of the HBO cult-hit series Tenacious D: The Greatest Band on Earth. Since then, Tenacious D has released two albums and a pair of live DVDs, sold out arenas around the world and starred in their own feature-length movie, Tenacious D in the Pick of Destiny. At the BlizzCon closing ceremony on October 23, the band will perform an earth-shattering set that includes the debut of new, soon-to-be-legendary songs.

“The best way to wrap up two days of epic entertainment is with an epic rock concert—and few bands fit the bill like Tenacious D,” said Mike Morhaime, CEO and cofounder of Blizzard Entertainment. “We’re looking forward to a great show and can’t wait to see what Jack and Kyle have in store for everyone attending BlizzCon and watching from home.”

In addition to serving as a gathering place for the Blizzard Entertainment gaming communities, BlizzCon will have an array of activities, including discussion panels, competitive and casual tournaments, contests, hands-on playtime with current and upcoming Blizzard Entertainment games, and more. Viewers at home can order a BlizzCon Virtual Ticket for $39.95 USD, available as a multi-channel Internet stream around the world (pricing and availability may vary by region) and also via DIRECTV in the United States . Visit www.blizzcon.com for more details and ordering information.

To keep pace with the continued growth of World of Warcraft as well as development on other Blizzard Entertainment games, the company is currently hiring for numerous open positions.
