Technological change is a term that describes a period of rapid change in technological systems and practices. Technological change occurs through three interacting forces. These forces are cultural, technological, and economic. Cultural change occurs through what people buy, use, and create; technological change occurs through what people are able to do because of new technologies, equipment, and devices that are available. Economic change occurs through what people sell, buy, and generate; technology changes through what people are able to produce, purchase, and build.
