Xbox One
In short
A home video game console developed by Microsoft as the successor to the Xbox 360. It was released in late 2013 and serves as the eighth generation of the Xbox series.
In plain words
It is a machine you plug into your television to play video games. It can also be used to watch films, use apps, and stream media. It was designed to be an all-in-one entertainment system.
A simple example
A player connects the console to their TV and uses a wireless controller to play games like Halo or Forza.
Why it matters
It helped Microsoft expand its presence in the living room through media integration. It also introduced many modern features like social sharing and digital game libraries.
Easy to mix up
Do not confuse it with the Xbox Series X, which is the much more powerful newer model.
