What is the correct way to capitalise the name 'XBOX'?

I've always written 'Xbox' myself, but saw 'xBox' today and realised I would like some clarification on the right way to write it.

In fact, is it even one word? Is it 'X Box'?

Is there a correct way at all?


Solution 1:

It's Xbox. Can't get more official than the official website.
