Sign of the times
Call of Duty: Black Ops has broken the $1 billion (£647 million) sales barrier, figures show.
Sales results released by publisher Activision Blizzard suggest it took just six weeks to do it.
In doing so it joins an elite group of entertainment releases to reach the billion dollar mark.
Others include Michael Jackson's Thriller album and James Cameron's 1997 hit film Titantic.
According to Activision, more than 600 million hours have been logged playing the game since its worldwide launch.
