Microsoft has given the world the first look at its new game console, hoping the newly named Xbox One will build on a solid core of gamer fans and become a hub for living room entertainment.
The third-generation console, coming eight years after the Xbox 360, was unveiled by games chief Don Mattrick at an event at the software company's campus near Seattle.
The new Xbox interacts with a user's television, responds to voice commands, and includes Skype video calling.
