Equivalent to 237,405 years of non-stop play, reckons Microsoft.
Xbox LIVE users have spent over 2 billion hours playing multiplayer games over the online service, Microsoft has revealed.
A total of 2,081,054,696 hours have been racked up by users playing multiplayer games over Xbox LIVE since the service went live in November 2002, with a further 603,549,497 hours spent using entertainment apps, including Netflix, Sky and BBC iPlayer.
The figures exclude the amount of time players have spent playing single-player games or simply being logged into the service.
In addition, Microsoft says that 122,265,266 friendships have been formed across Xbox LIVE.
Xbox LIVE celebrated its 10th anniversary last week, during which people spent more time on Xbox LIVE than any other week in the service's history. 442 million hours were spent on the service following the release of Halo 4 and Call of Duty: Black Ops 2.
To celebrate, Microsoft sent some of Xbox LIVE's longest serving members exclusively-designed Xbox 360 consoles. Did you get one?
