Rockstar parent Take-Two has splurged the news that GTA IV has topped a massive $500 million in sales in its first week of release.

It's additionally confirmed that GTA IV's sold around six million units to date, approximately 3.6 million of which went on opening day.

That means GTA IV has broken all entertainment records for day one and week one sales by dollar value, according to the publisher. Should you want some kind of comparison, Halo 3 did $300 million in its first week (although that was on a single platform).

"We knew Grand Theft Auto IV would break new ground in terms of the player's experience, with its compelling story line, extraordinary gameplay and action that ranges over a broad urban canvas. Now, it has broken sales and rating records as well," said Strauss Zelnick, Chairman of Take-Two.

"Grand Theft Auto IV's first week performance represents the largest launch in the history of interactive entertainment, and we believe these retail sales levels surpass any movie or music launch to date. We congratulate the entire Rockstar team on creating a must-have experience that takes the legendary Grand Theft Auto franchise to a new level."
