Commodification and commoditization

The dispute between the terms of commodification (Marxist political theory) and commoditization (business theory) was first highlighted by Douglas Rushkoff.[4]. Douglas highlighted that the words Commodification and Commoditization were used to describe the two different processes between the assignment of value to a social good and the movement towards undifferentiated competition. Rushkoff's outlined an approach which is closer to the common usages of the words.
Commodification (1975, origins Marxist political theory.) is used to describe the process by which something which does not have an economic value is assigned a value and hence how market values can replace other social values. It describes a modification of relationships, formerly untainted by commerce, into commercial relationships.
Commoditization (early 1990s, origins Business theory) is the process by which goods that have economic value and are distinguishable in terms of attributes (uniqueness or brand) end up becoming simple commodities in the eyes of the market or consumers. It is the movement of a market from differentiated to undifferentiated price competition and from monopolistic to perfect competition.
