Why is 'Mathematica' written in italics?

Software titles are usually not written in italics (e.g. “Microsoft Word”), but Mathematica always seems to be italic. Is there any reason for this, or is just the Wolfram house style?
(I promise this question isn’t completely irrelevant! I haven’t been able to find the answer anywhere else, so I thought I’d ask here.)
Thanks

I think that the italicization comes from the trademarked presentation of the name itself:

So it is not, in effect italicizing the name, but rather it is presenting the trademark as the name.

Thanks! That answer makes sense to me.
