Commercialization or commercialisation is the process of introducing a new product or production method into commerce—making it available on the market. The term often connotes especially the entrance into the mass market as opposed to earlier niche markets, but it also includes a move from the laboratory into even limited commerce. Many technologies begin in a research and development laboratory or inventor's workshop and are not practical for commercial use in their infancy (as prototypes). The development segment of the research and development spectrum requires time and money as systems are engineered  that will make the product or method a paying commercial proposition. The launch of a new product is the final stage of new product development and the one where advertising, sales promotion, and other marketing efforts encourage commercial adoption of the product or method. Beyond commercialization (in which technologies enter the business world) can lie consumerization (in which they become consumer goods, as when computers went from the laboratory to the enterprise and then to the home, pocket, or body).
