Media consumption or media diet is the sum of information and entertainment media taken in by an individual or group. It includes activities such as interacting with new media, reading books and magazines, watching television and film, and listening to radio. An active media consumer must have the capacity for skepticism, judgement, free thinking, questioning, and understanding.〔(【引用サイトリンク】url=http://mediactive.com/2-0-chapter-2-becoming-an-active-user-principles/ )〕 ==History== For as long as there have been screens, cameras, and photos, the people of the world have been consuming media. Around 1600 the camera obscura was perfected. Light was inverted through a small hole or lens from outside, and projected onto a surface or screen, creating a moving image. At this point in time, media consumption had a very small effect on society compared to today. In the 1860s mechanisms such as the zoetrope, mutoscope and praxinoscope that produced two-dimensional drawings in motion were created. They were displayed in public halls for people to observe. This was one of the first displays of media to the public in the way that it is consumed today. Around the 1880s, the development of the motion picture camera allowed individual component images to be captured and stored on a single reel. Motion pictures were projected onto a screen to be viewed by an audience. This moving camera affected the progression of the world immensely, beginning the American film industry as well as early international movements such as German Expressionism, Surrealism and the Soviet Montage. For the first time people could express themselves through the medium of film, and distribute their works to consumers worldwide. In San Francisco on Sept. 7, 1927, the electronic television was first successfully demonstrated. The system was designed by Philo Taylor Farnsworth, a 21-year-old inventor who had lived in a house without electricity until he was 14. By 1941 the Columbia Broadcasting System (CBS) was broadcasting two 15-minute newscasts a day to a tiny audience on its New York television station. However, the television industry did not begin to boom until the end of WWII. Eventually television began to incorporate color, and multiple broadcasting networks were created. In the 1960s the first computer was created. in 1975 the first computers made for consumers were released by IBM. Two years later Apple, a new competitor, came out with their first computers. On August 6, 1991 the internet and World Wide Web became available to the public. This was the start of the easily formatted internet that people use today. In 1999, Friends Reunited, the first social media site, was released to the public. Since then, Myspace, Facebook, Twitter and other social networks have been created. Facebook and Twitter are the top social media sites in terms of usage. Facebook has a total of 1,230,000,000 consumers while Twitter has 645,750,000. Both companies are worth billions of dollars, and continue to grow. Overall media consumption has immensely increased over time, from the era of the introduction of motion pictures, to the age of social networks and the internet. 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「Media consumption」の詳細全文を読む スポンサード リンク
