Consumer electronics are electronic equipment intended for everyday use, most often in entertainment, communications and office productivity. In British English they are often called brown goods by producers and sellers.〔(【引用サイトリンク】title=brown goods )〕 Radio broadcasting in the early 20th century brought the first major consumer product, the broadcast receiver. Later products include personal computers, telephones, MP3 players, audio equipment, televisions, calculators, GPS automotive electronics, digital cameras and players and recorders using video media such as DVDs, VCRs or camcorders. Increasingly these products have become based on digital technologies, and have largely merged with the computer industry in what is increasingly referred to as the consumerization of information technology. The CEA (Consumer Electronics Association) estimated the value of 2007 consumer electronics sales at US$150 billion. ==History== For its first fifty years the phonograph did not use electronics. However, in the 1920s radio broadcasting became the basis of mass production of radio receivers. The vacuum tubes that had made them practical were used to improve record players as well. Television was soon invented but remained insignificant in the consumer market until the 1950s. The transistor, invented in 1947 by Bell Laboratories, led to significant research in the field of solid-state semiconductors in the early 1950s. The transistor's advantages revolutionized that industry along with other electronics. By 1959 Fairchild Semiconductor had introduced the first planar transistor from which come the origins of Moore's Law. Integrated circuits followed when manufacturers built circuits (usually for military purposes) on a single substrate using electrical connections between circuits within the chip itself. Bell's invention of the transistor and the development of semiconductors led to far better and cheaper consumer electronics. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Consumer electronics」の詳細全文を読む スポンサード リンク
