By 1999, consumer products making use of nanotechnology started appearing in the global market place. Products such as automobile bumpers that resisted denting, golf ball that flew straighter, tennis rackets that were stiffer, scratch-resistant glass coatings, faster-recharging batteries for cordless electric tools, and improved displays for televisions, cell phones, and digital cameras were introduced to the global market and were all credited to nanotechnology. The science was significant that Bill Clinton, in 2001, established the National Nanotechnology Initiative to provide federal support to promote United State’s competitiveness in nanotechnology. In 2003, Congress followed with the enactment the 21st Century Nanotechnology Research and Development Act. The act provided funding and promoted research to address key issues.
