‘Call of Duty’ Nets $1 Billion

So you want to be prepared for the near-future, when the U.S. has become an international underdog? Don’t laugh, that’s the plot of the hugely successful Call of Duty, which brought in a $1 billion in sales in its first day on the market Tuesday. Call of Duty: Ghosts is the first video-game franchise to make that much in its first day, the publisher said Wednesday. The game is a military fighting game written with the help of Oscar-winning Traffic writer Stephen Gaghan.
