Activision Blizzard Inc said it sold 4.7 million copies of "Call of Duty: Modern Warfare 2" for $310 million on its first day, setting a new record for the video game industry.
The shooting game went on sale on Tuesday in the most highly anticipated debut of the year. Fans had lined up for hours outside retail stores like GameStop in advance of the midnight release.
Analysts projected unit sales of 11 million to 13 million by the end of 2009, saying "Call of Duty" would defy the weak economy because it appeals to hard-core gamers willing to shell out $60 for the title. Estimates for launch-day sales ranged from $300 million to $340 million.
