Experts say the numbers underline the growing power of the games industry, which - with forecasts of $14bn in games sales for the three major consoles in 2008 - is eclipsing other major entertainment industries, including cinema. In fact, GTA IV is expected to earn more during its first few days of release than the $400m made by the third instalment of Pirates of the Caribbean, the Hollywood record holder, in its opening weekend.
The film magazine Variety has suggested the game's success could affect interest in this summer's blockbusters, which may struggle to compete for the same audience of young men.
Iron Man, the high-octane movie based on the comic book character, which is expected to be one of the year's biggest action films, is just one of those which could be harmed by going on release the same week as Grand Theft Auto IV.
