And this morning CEO Meg Whitman (pictured) will open trading on the New York Stock Exchange as the CEO of Hewlett Packard Enterprise (HPE).
The other bit of HP will be headed by Dion Weisler.
Over the last three months or so, both companies have been working out how the nuts and bolts of both businesses work, and have already divided their support web sites so that if you need a bug fix or an upload, you get directed to the relevant pages.
HPE will deal as its name suggests with the enterprise side of business, while HP Inc will carry on selling printers, PCs and the like.
The split actually happened yesterday after HP’s Whitman said it would divide itself in two in early October.
HP was formed by Dave Packard and Bill Hewlett and went into business in 1939.
HP had a rough time in the early years of this century under the stewardship of Carly Fiorina. Then followed Mark Hurd, who now works for Oracle, followed in rapid succession by Leo Apotheker, who mastermind buying Autonomy for $10 billion.
He only lasted for just under a year.
