The Xbox One launched in 13 territories of November 22, 2013 8 years to the day after the release of its predecessor, the Xbox 360. Just 24 hours later, Microsoft announced the Xbox One had sold one million units, an accomplishment that beat out the 360's launch, but followed the same initial sales trajectory of its main rival, Sony's PS4. Microsoft's direction with the Xbox One has evolved since its initial launch, and while console sales have been solid, they still haven't managed to keep pace with the PS4.
