According to a report in the NYT, Grand Theft Auto IV reached sales of over $500 million in its first seven days on the market. Take Two Interactive said the game sold approximately 6 million copies worldwide since its launch last Tuesday.
The numbers significantly exceeded expectations of many analysts who expected to see around 5 million copies sold in the first two weeks. Take Two also stated that 3.6 million of those copies were sold the first day of the launch globally for around $310 million in sales. This number even exceeds the numbers we saw for the Halo 3 launch for both first day and first week sales.
