Call Of Duty series tops 55 million sales

The Call Of Duty series has surpassed 55 million unit sales to date worldwide, taking a whopping $3 billion in retail sales in the process.

That’s according to a combination of data from The NPD Group, ChartTrack, GfK and internal Activision estimates, released today by the publisher.

The series has hit the figures after Modern Warfare 2 shattered box office and video game records with a worldwide estimated five-day sale through of approximately $550 million.

"Call Of Duty has become one of the greatest entertainment franchises of all time," said Bobby Kotick, CEO of Activision Blizzard.

"If you consider the number of hours our audiences are engaged in playing Call of Duty games, it is likely to be one of the most viewed of all entertainment experiences in modern history."
