Blizzard previously announced that this first expansion set for World of Warcraft sold through nearly 2.4 million copies worldwide in its first 24 hours — more than any other PC game in history had sold within an entire first month of availability.* With approximately 3.5 million copies sold through, The Burning Crusade has now established the new one-month record for PC-game sales.
Amazon.com reported that it received more preorders for World of Warcraft: The Burning Crusade than for any other PC or console game ever, and Wal-Mart also recorded similar record-breaking numbers for The Burning Crusade. According to Gary Severson, senior vice president and general manager at Wal-Mart, "Not only was The Burning Crusade the top-selling item in our electronics department the day it released; it had the best day-one sales of any PC-game launch in our company's history."
