Prosumer is a portmanteau formed by contracting either the word professional or, less often, producer with the word consumer. For example, a prosumer grade digital camera is a « cross » between consumer grade and professional grade.
The term has also taken on multiple meanings in business and economics: the business sector sees the prosumer (professional–consumer) as a market segment, whereas economists see the prosumer (producer–consumer) as having greater independence from the mainstream economy. These differing meanings often describe the same people; consumers unusually interested in the products. It can also be used to differentiate the traditional passive consumer with an active consumer role more involved in the process, such as activity in the design or customization of the end product.
