For some reason, Activision Blizzard is using global box office numbers in its comparison of the sales figures of Call of Duty: Modern Warfare 2. However, when you post nearly one billion dollars in revenue over a weekend, heck, you can do what you want.
According to Activision Blizzard, Modern Warfare 2 has sold $800 million worth of copies in its first weekend, which is higher than the previous record-holder, 2011's Modern Warfare 3. The game's predecessor/sequel (we know, the naming gets confusing) took more than five days to post similar numbers and a little over two weeks to hit a billion. Modern Warfare 2 should hit similar figures in a few days.
With its numbers, the only game to beat Modern Warfare 2 is Grand Theft Auto 5.
Modern Warfare 2's success is unprecedented but it's not unexpected. After back-to-back sub-par years, Activision Blizzard wants to make a statement with Modern Warfare 2, and it's safe to say it has accomplished its mission.
