Original equipment manufacturer, or OEM, is a term that refers to a situation in which one company purchases a manufactured product from another company and resells the product as its own, usually as a part of a larger product it sells. OEM is the company that originally manufactured the product.
The term OEM (original equipment manufacturer) was coined in the 1950s by IBM. It designated a customer that purchased IBM computers and resold them as part of a larger product. The first OEMs sold oil refineries.
When a company purchases products or components from another company and resells the products or components with the purchasing company's name or logo on them (usually, but not always as part of a product), the company that resells the product is called the OEM.
There is a growing market for the sales of OEM products directly to end users via online auction sites and such. An OEM product will differ from its retail version in price, the extent of the warranty, parts, instructions, and sometimes even functionality. OEM hardware can be purchased by end users at considerable savings of 30% or more. For example, OEM hard drives are purchased in a simple plastic bag without the additional cables or bulky box found in the more expensive retail package.
Original Design Manufacturer
The term Original Design Manufacturer (ODM) is used to describe companies that design and manufacture a product that is then sold under other brand names and does not necessarily acknowledge the Original Design Manufacturer brand. Some OEMs (original manufacturers, not resellers) have taken on a larger role in the design of the product they are manufacturing and become ODMs.
