After breaking records for first-day sales, GTA IV has continued that success, furthering it into this week. With less than 10 days behind the game going gold, GTA IV now has broken first-week sales records with an estimated 6 million copies sold worldwide. That represents half a billion in sales, and obviously is making both Take Two and Rockstar very happy.

The new game has sparked off a slew of controversies, from crazy lawyers to city officials and more. Despite that, people have swarmed to the game. Interestingly, a Take Two Chairman made the assertion that GTA IV, and perhaps other titles in the future, is surpassing movies and music for sales figures on a launch day. That's quite a difference when we can all remember a time not too far back when video games were a drop in the bucket.
