Microsoft's Games with Gold will offer Xbox One owners a total of five free games to download in December. Two of them will be Xbox One native games while the other three will be Xbox 360 games that can be played via the Xbox One's backwards compatibility feature.
Xbox Live is Microsoft's digital media delivery service perhaps best known for its connection to online gaming on the Xbox 360 and now the Xbox One. Originally it actually launched back in 2002, the days of the original Xbox, with updated versions coming in 2005 with the Xbox 360 and again in 2013 with the Xbox One.
Xbox Live has also extended beyond the Xbox consoles, with an integration in Windows gaming and Windows Phone. With the forthcoming launch of Windows 10, Xbox Live will grow again.
