WoW: Burning Crusade on Fire

World of Warcraft: The Burning Crusade Shatters Day-1 Sales Record is a press release that wows us with word that the new WoW expansion sold more copies in its first 24 hours than many games will sell in a lifetime, with more that 2.4 million copies sold:
Day-one sales totals on both continents were similar, with an estimated total of nearly 1.2 million copies sold on the first day in North America and an estimated total of more than 1.1 million copies sold in Europe within the first 24 hours of launch(a). By the end of the first day of availability on both continents, a total of more than 1.7 million players had already logged in and upgraded World of Warcraft to play The Burning Crusade.
