BBC reports Microsoft will be discontinuing production of the Xbox 360. The game console was originally released all the way back in 2005 as a 2nd-generation to the Xbox. Xbox boss Phil Spencer said more than 78 billion (78,000,000,000) hours of gameplay had taken place since then on the system. All remaining systems would be sold and support would be ongoing for players. However, all Xbox 360 games are now backwards compatible with the 3rd-generation Xbox One.
