Many of the gamer web sites and the Gamer review, and forum websites have tendencies to refer to The PlayStation part of Sony as a Division of Sony..this is completely incorrect. There is a big difference between the two terms & structure in Business.
This blog post is to clarify and show just some of the Differences.
What is the difference? Look and See for yourself.
Well it's defined, by many Business structure definition as such.
Difference Between Division and Subsidiary
Division vs Subsidiary
A division is a part of a business entity. This means that a division, although it operates in a different name, is still a piece of the entity itself. On the other hand, a subsidiary is an entirely different company, a separate one, which is owned by another usually bigger entity. But in some cases, the parent company is a much smaller entity than that of the subsidiary company. In a more concrete analogy, you can say that a division is a part of the body, let us say hand, for instance, and while a subsidiary is the offspring with an entirely separate body but is still owned by the parent company.
Another difference between a subsidiary and a division is that the subsidiary can perform an entirely different operation from that of its parent company while a division cannot.
1.A division still operates as part of the parent company, although it has a different name, while a subsidiary is a totally separate company from the parent company.
2.A division’s operations should be related to the operations of the parent company while a subsidiary company’s operations need not to be in line with its parent company’s operations.
3.The condition of the division will greatly affect the parent company while the condition of a subsidiary will not have any effect on the parent company.
SIE is a wholly-owned subsidiary of Sony Corporation and has global functions and regional headquarters in California, London and Tokyo.
As you can See, the PlayStation is a separate structure of Subsidiaries that are several separate entities under the PlayStation Subsidiary LLC.
