    BlizzCon Online Contests
    We’ve just released some new information about the three online contests for this year’s BlizzCon:

    BlizzCon Fan Art Contest
    Blizzard Entertainment is proud to announce our official BlizzCon Fan Art Contest! We’re looking for some talented artists to draw their favorite character or monster from the Warcraft, StarCraft, or Diablo universes in a recognizable in-game location. We’ll be posting the winning submissions on our site, and we’ll also be prominently displaying them next to original artwork from our titles in the art gallery at BlizzCon 2007!

    Visit our fan art contest page for more information.

    BlizzCon Original Song Contest
    Music can set the mood, lift spirits, and create suspense. It is a part of our everyday lives and can help create lifelong memories. Enter to win the BlizzCon Original Song Contest and your song could be a part of a BlizzCon 2007 memory.

    BlizzCon Movie Contest
    Ever wanted to share your tales of action, hilarity, or epic drama with an equally epic audience? Here’s your chance to bring the untold stories of Azeroth to light in this year’s BlizzCon movie contest. Contestants are challenged with creating an original and compelling story told within the daily lives of the denizens of the world of Warcraft, and the winners will have their work unveiled at BlizzCon.
