Consumer electronics refers to any device containing an electronic circuit board that is intended for everyday use by individuals. This encompasses a massive category of electronics that includes televisions, cameras, digital cameras, PDAs, calculators, DVDs, clocks, audio devices, headphones, camcorders, and many other home related products. The electronics revolution is rapidly changing the world, whether we are at home, at work, out for a shopping. Consumer electronics involves using devices called components to control an electric current, which flows off tiny, electrically charged particles of matter called electrons. There is an ever increasing need to keep the product information updated and most comparable, for the consumer to be able to make an informed buying decision. While consumer electronics continues in its trend of convergence, combining elements of many consumer electronic items, the consumer faces different decisions when purchasing their items. A recent trend in many types of consumer electronics is connectivity. It's usual for many products to include Internet connectivity using technologies such as Wi-Fi, Bluetooth or Ethernet. Currently, the global consumer electronics industry is mainly dominated by Japanese, South Korean and American companies.
