INNOVATION: The introduction and dissemination of a new idea, product, or technological process throughout society and the economy. The innovation process should be contrasted with the act of invention, which is the creation of something new, but not the dissemination. Innovations are often though of as applying to physical products and technology. However, it applies to all aspects of society and the economy--physical, tangible, ideological, cultural, and social. Innovation often leads to the widespread use of new products (such as computers and DVD players), but it also creates new cultural, social, and economic institutions (such as government agencies, forms of business organizations, and social trends). Innovations are consider to be a primary source of economic growth.
