Should the company Loew's Incorporated be entered into profiles as Loew's or Loew's Incorporated.

From the early 20's until the late 50's, it was the parent company of Metro-Goldwyn-Mayer and appears on many many films during the credits, usually as something like "Copyright (year) in USA by Loew's Incorporated".

The contribution rules tell us to "omit company suffixes such as LLC, Ltd., Inc."

Is Incorporated in this case actually part of the company's name, or is it just a suffix? (It always appears as Loew's Incorporated and I can't recall ever seeing it appear as Loew's Inc.)

I don't really know much about this stuff, so wanted to ask, because in my local, I have dozens of profiles that contain just "Loew's" and dozens of profiles that contain "Loew's Incorporated" and it seems that a bunch of folks enter it as one way and a bunch enter it as another, and I'd just like to have some consistency as to how it's entered.

Thanks in advance for any help or info shared!
