For comparison, the previous record holder was last years Call of Duty: Black Ops 2, which reached $1 billion in fifteen days, five times as long as it took Rockstar's latest effort. The development commented on the feat, saying "We believe this marks the fastest that any entertainment property, including video games and feature films, has reached this significant milestone."
By the time the game was released, it was estimated to have cost a combined $265 million for developing and marketing, which not only makes it the most expensive videogame ever made, but that's a higher budget than most Hollywood blockbusters. After receiving almst universal acclaim from critics and fans alike, it's good to see Rockstar's efforts being rewarded.
