A prospective consumer who is involved in the design, manufacture, or development of a product or service is called a "prosumer." The document provides an example of prosumers as a group of people giving input into a new shampoo via a poll or similar activities. It also briefly discusses the book "Wikinomics" which describes how new collaborative online enterprises like MySpace, InnoCentive, Flickr, Second Life, and YouTube allow masses of people to participate in the economy in new ways.
