What is an 'Original Equipment Manufacturer - OEM'
In its traditional definition, an original equipment manufacturer (OEM) is a company whose goods are used as components in the products of another company, which then sells the finished item to users. This firm is referred to as a value-added reseller (VAR) (because by augmenting or incorporating features or services, it adds value to the original item) works closely with the OEM, which often customizes designs based on the VAR company's needs and specifications.
One of the most basic examples is the relationship between an auto manufacturer and makers of various auto parts. Parts such as exhaust systems or brake cylinders, are manufactured by a wide variety of OEMs. The OEM parts are then sold to an auto manufacturer, which then assembles them into a car. The completed car is then marketed to auto dealers to be sold to individual consumers.
However, there is a second, newer definition of OEM, typically used in the computer industry. In this case, OEM may refer to the company that buys products and then incorporates or rebrands them into a new product under its own name. For example, Microsoft supplies its Windows software to Dell Technologies, which incorporates it into its personal computers and then sells a complete PC system directly to the public. In the traditional sense of the term, Microsoft is the OEM and Dell the VAR. However, the product guide for the computer is most likely to refer customers to Dell as the OEM.
In other words, OEM can mean the company that sells a component to a VAR; but in some cases, it refers to the VAR acquiring a product from an OEM. If this sounds confusing – it is.

Why Does OEM Have Opposite Meanings?
This somewhat contradictory evolution in the use of the term OEM (which can also be used as an adjective, as in "OEM parts" or even a verb, as a manufacturer saying it plans to OEM a new gizmo) is normally attributed to the computer hardware industry. Some VAR companies such as Dell, IBM and Hewlett Packard started to accept branded parts from outside sources in their own products.
How OEMs Work
However squishy the definition, the fact remains that VARs and OEMs work together. OEMs make sub-assembly parts to sell to VARs. Although some OEMs do make complete items for a VAR to market, they usually don't play much of direct role in determining the finished product. A common example might be the relationship between an OEM of individual electronic components and a company such as Sony or Samsung that assembles those parts in making its HDTVs. Or, a maker of buttons who sells its little fasteners to Ralph Lauren, sometimes customized with the letters RL stamped on them. Typically, no one integrated part from an OEM is recognized as playing an especially significant role in the finished product, which goes out under the corporate brand name.
Traditionally, OEMs focused on business-to-business sales, while VARs marketed to the public or other end users. However, an increasing number of OEMs are selling their parts or services directly to consumers (which, in a way, makes them a VAR!). For example, people who build their own computers can buy graphics cards or processors directly from Nvidia and Intel or retailers that stock those products. Similarly, if a person wants to do his own car repairs, he can often buy OEM parts directly from the manufacturer or a retailer that stocks those parts.
OEM vs. Aftermarket
OEM is the opposite of aftermarket. OEM refers to made specifically for the original product, while aftermarket refers to equipment made by another company that a consumer may use as a replacement..
For example, say a person needs to replace his car thermostat, created expressly for his Ford Taurus by ABC Thermostats. He may buy the OEM part – a duplicate of his original ABC thermostat, used in the original manufacturing of the vehicle. Or he may buy an aftermarket part, an alternative made by another company. In other words, if the replacement also comes from ABC company, it is OEM; otherwise it is aftermarket.
Usually, consumers buy an aftermarket product because it's cheaper (the equivalent of a generic drug), or more convenient to obtain. But sometimes OEMs do such a good job in manufacturing a specific part that it becomes known to consumers, who actively seek it out. An example of this is the success of Hurst Performance of Warminster Township, Penn., a manufacturer of gear shifters for automobiles. Hurst shifters became so well-known for their superior performance that car buyers would insist on them as a replacement part, or sometimes even purchase and install them before the originals even needed replacing.
