While the term OEM (original equipment manufacturer) was coined decades ago to explain software integration onto hardware, OEM today means many things to many people.  It continues to be used to explain embarked software onto “equipment” (whether that be a smart phone, a refrigerator, a car, a printer, or anything else you can think of); it is also a term that is used to describe ISV-to-ISV partnerships to embed one piece of software into another.
