Forget the opening day sales record of Harry Potter and the Deathly Hallows Part 2 , which earned $91 million last July 15 and went on to earn $381 million domestically. A video game, Activision Blizzard's "Call of Duty Modern Warfare 3," raked in $400 million from sales in the U.S. and the U.K. within 24 hours after it was launched last Tuesday, according to Charttrack. In a statement Activision Blizzard CEO Bobby Kotick said, "We believe the launch of Call of Duty Modern Warfare 3 is the biggest entertainment launch of all time in any medium, and we achieved this record with sales from only two territories."
