Blizzard Entertainment today announced that World of Warcraft: Wrath of the Lich King sold more than 2.8 million units in its first 24 hours of availability, making it the fastest-selling PC game of all time.

The previous record was held by World of Warcraft: The Burning Crusade which sold an impressive 2.4 million units on day one back in January 2007.

"We're grateful for the incredible support that players around the world have continued to show for World of Warcraft," said Mike Morhaime, CEO and co-founder of Blizzard Entertainment. "Wrath of the Lich King contains some of the best content we've created for the game so far, and we look forward to seeing even more players log in to experience it in the days ahead."
