9 大群體傳播 演講 授課 大眾媒介 中心式的發訊者對個別 的受訊者 報紙 電視、無線電廣播

10 新的科技與大眾媒介 大眾媒介的發訊者 宣偉伯 (Wilbur Schramm) — 提出大眾 媒介之傳統定義 議題設定 (agenda setting) — 由守門 人 (gatekeepers) 的精英人員,決定受 眾應該接收哪些訊息

11 大眾媒介的訊息 從前,大眾媒介的訊息並未經過區隔 化,而僅是將其傳送給盡可能多數的 受訊者 ; 首要策略是將受訊者的喜好 及觀念加以均質化 (homogenize) , 以達成工業化社會中的大量市場目標 新的大眾媒介更傾向於迎合特定的群體, 甚至不斷的界定出新群體

12 大眾媒介管道 每一種媒介均需要有為特定目標而 設傳送或分配系統,其訊息也非是永久 性的 目前的管道數量與種類,產生了極 大的改變

13 大眾媒介的受眾 傳統觀念  受眾是一個未經區隔化的群體 大眾媒體訊息  受眾是一群沉默的接受者 媒介的經濟狀況  需要受眾來製造或維繫 大眾媒介系統所花費的 巨額支出,盡可能的由 這些廣大的受眾身上取 得

14 傳播媒介與傳播科技的重要性 大眾媒介與資訊科技之融匯與市場結合 的概念的代表意義 傳播的種類 傳播的互動性 新的科技對大眾媒介的影響 ? 市場將如何 受影響 ?

15 Communication Technology What is it? Provides a transfer of knowledge to people all over the world. Records, stores, manipulates, analyzes, and transmit data. Includes computers, graphic media, electronic transmitters, recognizing devices, and entertainment products etc. Deals with information in digital form.

16 Communication Technology: Why is it Important? Assist people in making decisions and solving problems Allow individuals research and check out facts of messages Form of entertainment: Radio, movies, TV, videogames. Gather facts on how to use other technologies to help society Understand influences of technology (i.e., timing culture, sequencing etc.)

17 MILESTONES IN COMMUNCATIONS Early words (3500-1BC) Printing (AD100-1600) Cameras and microphones (1700-1840) Telegraphs and telephones (1850-1900) Pictures — still and moving (1880-1900) Entertainment and information (1900- present)

18 Early words (3500-1BC) In about 3500 BC ancient Egyptians used papyrus, pressed into flat sheets, as a writing surface. Later they used parchment (the dried skin of animals like sheep). In around 3000 BC the ancient Sumerians of Mesopotamia developed cuneiform writing. Having a writing system allowed people for the first time to record information and ideas. By about 1700 BC a 22-letter alphabet was used by the ancient Phoenicians. In about 1100 BC the first dictionary was compiled by the Chinese. Paper was invented by the Chinese in about 140 BC, but there is little evidence that it was used for writing at the time. By 40 BC the library at Alexandria in Egypt was the greatest storehouse of knowledge in existence, containing more than 400,000 scrolls. In around 5 BC Roman physician Celcus compiled an early encyclopedia, devoted to medical subjects. The modern encyclopedia was published on 1728 by British publisher Ephraim Chambers(c. 1680- 1740).

20 Printing (AD100-1600) In the first millennium AD, China was the source of a number of important inventions for communicating. In 110 the oldest surviving writing paper was made in China. In 748 the world ’ s first printed newspaper was produced in Beijing, China. By 751 the earliest printed text, a Buddhist scroll, was completed. Arab physicist Alhazen (965-c. 1040) proposed a way of studying an eclipse of the sun, which formed the basis of the pinhole camera, or camera obscura, described by Leonardo da Vinci in the 1400s and invented in 1570 by Giovani Battista della Porta.

21 Printing (cont.) In about 1045, the Chinese were printing using movable type, an invention that was developed in Europe 400 years later, in 1453, by German printer Johannes Gutenberg (1400-1468). The first English book was printed in 1474 by William Caxton (c.1422-c.1491). In 1107 printing with several colors was developed in China, initially to make the forgery of paper money more diffcult. In 1155 the earliest known printed map was produces in China. By 1189 the earliest paper mill in Europe was established. By about 1250 the quill pen (goose feather) became the most popular writing instrument in Europe. In 1565 German natural scientist Konrad Gessner (1516-1565) invented the graphite-filled pencil.

22 Cameras and microphones (1700-1840) The year 1702 saw the launch of the Daily Courant in London, Britain ’ s first daily newspaper. In 1725 French inventor Basile Bouchon devised the punched- card system to control a loom; this was the forerunner of computer programs. In 1796 Czech printer and playwright Alois Senefelder (1771- 1834) invented lithography, a nonrelief printing method using limestone and frease. He used the process, which he discovered by accident, as an economic way to duplicate his scripts. In 1824 French teacher Louis Braille (1809-1852), blind from age 3, invented a raised-point writing system for the blind. In 1839 the earliest photographic print on silver chloride paper was made by British physicist W. Fox Talbot (1800-1877). In the same year, the daguerreotype photographic process was invented by French painter Jacques Daguerre (1789-1851).

23 Telegraphs and telephones (1850-1900) Scientists had been experimenting with telegraphs for many years before British physicists Charles Wheatstone (1802-1875) and William Cooke (1806-1879) patented the telegraph in 1837. The invention transformed communications by making fast, long distance communication possible for the first time. In 1837, American inventor Samuel Morse first demonstrated his code for transmitting messages. Morse code became the standard used in telegraphy. The year 1854 saw the installation of an electric telegraph between London and Paris. In the same year, the cathode ray tube was invented by German glassblower Heinrich Geissler (1814-1879).

24 Telegraphs and telephones (cont.) In 1858 the first telegraph cables were laid across the Atantic Ocean. By 1872, most of the world ’ s major cities could communicate with one another by telegraph. In 1867 the mechanical typewriter was invented. In 1876 the telephone was invented by British-born American inventor Alexander Graham Bell (1847-1922). Several other scientists were working on the device on the device at the same time, but Bell was the first to receive a patent. The carbon microphone, developed by American inventor Thomas Edison (1847-1931) the following year, vastly improved the phone ’ s sound quality. In 1878 the first telephone exchange opened in New Haven, CT. The exchange offered a slow service until the mechanical automatic selector was designed a decade later. Electronic exchanges, providing an even faster service, were introduced in the 1960 ’ s.

25 Pictures — still and moving (1880-1900) In 1881 the earliest color photograph was produced by American invetor Frederick lves (1856- 1937). In the same year a forerunner of the movie camera was devised by French physiologist Etienne- Jules Marey (1830-1903) to analyze movements. In 1885 continuous photographic film was invented by American invetor George Eastman (1854- 1932), making cheap photography and moving pictures possible. In 1890 British inventor William Frieze-Green (1855- 1921) pioneered motion pictures, showing his first movie; he later devised color and 3-D cinematography.

26 Pictures — still and moving (cont.) In 1895 Italian inventor and electrical engineer Guglielmo Marconi (1874-1937) made his first successful transmission by wireless telegraphy, or radio. Six year later, he sent transatlantic radio signals for the first time. Commercial radio broadcasts began in the US in 1920, when station KDKA, Pittsburgh, PA went on air. Also in 1895, the cinematograph, a cinema projector, was used to project a moving film. In the late 1890 ’ s, the zoetrope was one of a number of optical toys that produced “ moving ” pictures. In 1896 American statistician Herman Hollerith (1860-1929) set up International Business Machines (IBM) after his success in using the punched-card system to process the 1890 US census.

27 Entertainment and information (1900-present) In 1904 gramophone records were invented. In 1924 American electrical engineer Edwin Armstrong (1890-1954) devised frequency modulation (FM), a static-free way of the transmitting radio signals that achieved great popularity with music stations in the 1950 ’ s and 1960s. In 1926 the first “ talkie ” motion picture – The Jazz Singer, starring AI Jolson-was released. During the same year, the television pictures were produced by British electrical engineer John Baird (1888-1946). Color television was first broadcast in 1940.

28 Entertainment and information (cont.) In 1936 paperback books were first marketed under the Penguin Books imprint. In 1937, American inventor Chester Carlson (1906- 1986) discovered the process of xerography, which was later developed by Xerox Corporation in photocopying machines. In 1952 the first transistor radio was developed by the Sony Corporation. In 1956 the first computer programming language, FORTRAN, was devised by IBM. Other computer languages developed later include COBOL and BASIC.

29 Entertainment and information (cont.) Audio cassettes were introduced in 1963, and video cassettes in 1969. In 1981, IBM launched the first personal computers (PCs), giving individuals access to computers for the first time. In 1982 compact disk (CD) players were introduced. CDs are a digital system of recording, as opposed to analog, and cannot wear out. In 1985 the CD-ROM (compact-disk read-only memory) was introduced, greatly expanding data storage capacity. The 1990s saw the introduction of the “ information superhighway. ” One aspect of this is Internet, which connects users to a range of information sources and activities – including newspapers, archives, and electronic mail — though computer link-ups and telephone lines. There are an estimated 15 million users in the US, and 25 million worldwide.

30 Satellite join to communication "Sputnik 1" was the first satellite in space. It was launched in October 4, 1957 by the USSR. It was a sphere with a diameter of 58 centimetres that weighed 84 kilogrammes.satellite
