Mass media
一碧万顷的意思Mass media are institutions of mass communication; they rve as the channels through which messages are pasd from the source to the destination. From the founding of the United States to the prent day, mass media have played an important role in nearly all the important events of the nation. Nowadays, new media has become a significant element in everyday life. The global network of the Internet connects people and information via computers. Mass media unquestionably influence every dimension of people’s lives.
Mass media denotes a ction of the media specifically designed to reach a large audience. The term was coined in the 1920s with the advent of nationwide radio networks,mass-circulation newspapers and magazines. However, some forms of mass media such as books and manuscripts had already been in u for centuries.
Mass media includes Internet media (like blogs, message boards, podcasts, and video sharing) becau individuals now have a means to exposure that is comparable in scale to that previously restricted to a lect group of mass media producers. The communications audience has been viewed by some commentators as forming a mass society with special characteristics, notably atomization or l
ack of social connections, which render it especially susceptible to the influence of modern mass-media techniques such as advertising and propaganda.The term public media is less ud and is defined as "media who mission is to rve or engage a public." Marshall McLuhan, one of the biggest critics in media's history, brought up the idea that "the medium is the message".
Mass media are very important tools of communication, through which information is pasd to even the farthest end of the world. They enable us to communicate with each other by helping us to overcome the barriers of time and apace.

1、TV
After World War II, people’s homes
were invaded by a powerful new force --
television. The idea of eing "live" shows
麦穗简笔画
in the living room was immediately
attractive. The effects of this powerful
medium are still being measured.
Television has developed since World War
下颌中切牙
II into the most popular medium in the US
and UK, one that has had great influence
agentina
on American way of life. Virtually every
American houhold -- 98% in 1999 -- has at least one TV t. Seven in ten Englishmen in 1991 reported getting most of their news from TV. Three large privately-owned networks -- NBC, CBS and ABC -- claimed 90 percent of the TV market from the 1950s through the 1970s with free broadcasts.
Cable Television
However, the rapid spread of pay cable TV in the 1980s broke the hegemony of the big three. By 1999, clo to 70% of American houholds had subscribed to cable TV. Cable TV, carried by coaxia
l and fiber-optic cables, originated in 1948 to better rve individuals in mountainous or geographically remote areas who could not receive over-the-air TV stations. The genesis of cable as it is known today stems from development of the domestic communications satellite, approved by the Federal Communications Commission in January 1973.
The new technology offered cable programmers a cost-effective method of national and international distribution. In December 1975, Home Box Office, an all-movie channel owned by Time, Inc., became the first programmer to distribute its signal via satellite. The next rvice to u the satellite was a local television station in Atlanta owned by Ted Turner. It became known as the first "superstation," bouncing its signal off a satellite to reach a nationwide audience. The same technology allowed Turner in 1980 to found the Cable News Network, CNN, the world's first 24-hour all-news channel. By early 1993, MTV, the leading American rock music TV network, had an audience of 46 million in the United States and 32 other countries. Cable television has also been successfully ud to reach very defined audiences. Beginning in the late 1970s, a growing number of U.S. cable systems began "narrowcasting" or offering television programming with an entire channel tailored to a narrow ction of the audience.
Advancing digital technology and increasing wiring of U.S. cities with fiber-optic cable that permits m
assive transmission of digital signals are giving cable TV subscribers a host of new interactive rvices. The convergence of the computer with TV is permitting a host of new "interactive" rvices in which the viewer no longer watches passively, for example "Movies on demand" which allows a viewer to choo between veral thousand videos is one interactive rvice. Another example is "shop-at-home" channels.
Public Television
U.S. public television stations are independent and rve community needs. All public television organizations are linked nationally, however, through three national organizations: the Corporation for Public Broadcasting (CPB), created by Congress in 1967 to channel federal government funding to stations and independent producers; the Public Broadcasting Service (PBS), formed in 1969 and which today distributes programming and operates the satellite system linking all public TV stations; and the Association of Public Television Stations (APTS), which helps member public TV stations with rearch and planning. In addition to the public TV stations, there are
a growing number of noncommercial stations run by Christian evangelistic ministries, which are, for the most part, supported by donations from viewers and member churches.
2、Magazines
The late 1800s saw the start of opinion journals still influential a century later, including the Atlantic Monthly, the Nation, and Harper's. The largest readerships were won, however, by magazines that catered to people's increasing leisure time and appetite for consumer goods, magazines such as Cosmopolitan, the Ladies Home Journal, and the Saturday Evening Post. Publishers were no longer just lling reading material; they were lling readers to advertirs. Becau newspapers reached only local audiences, popular magazines attracted advertirs eager to reach a national audience for their products. By the early 1900s, magazines had become major marketing devices.
At the same time, a new breed of newspaper and magazine writer was exposing social corruption. Called "muckrakers," the writers sparked public pressure for government and business reforms. Y
et magazines did not truly develop as a powerful shaper of news and public opinion until the 1920s and 1930s, with the start of the news weeklies. Time was launched in 1923 by Henry Luce (1898-1967). Intended for people too busy to keep up with a daily newspaper, Time was the first magazine to organize news into parate departments such as national affairs, business and science. Newsweek, using much the same format, was started in 1933. Other prominent news weeklies are Business Week and U.S. News and World Report.
Magazine publishers have increasingly tried to appeal to clearly-defined audiences. Computer technology has helped publishers to target special-interest audiences. As a result of this specialization, the number of periodicals published in the United States jumped from 6,960 in 1970 to clo to 10,000 in 1999.
3、Radio
The beginning of regular
commercially licend sound broadcasting
in the United States in 1920 ended the
print monopoly over the media and
问苍茫
opened the doors to the more immediate
and pervasive electronic media. By 1928,
the United States had three national radio
networks - two owned by NBC (the
National Broadcasting Company), and one
by CBS (the Columbia Broadcasting
System).
Though mostly listened to for entertainment, radio's instant, on-the-spot reports of dramatic events drew huge audiences throughout the Great Depression of the 1930s and World War II. President Franklin Roovelt recognized the potential of radio to reach the American public, and during his four terms (1933-1945), his radio "fireside chats" informed the nation on the progress of policies to count
er the Depression and on developments during World War II. After World War II, television's visual images replaced the audio-only limitation of radio as the predominant entertainment and news vehicle. Radio adapted to the new situation by replacing entertainment programs with a format of music intersperd with news and features. In the 1950s, automobile manufacturers began offering car radios as standard accessories, and radio received a big boost as Americans tuned in their car radios as they drove to and from work.
The expansion and dominance of FM radio, which has better sound quality but a more limited range than traditional AM, reprented the major technical change in radio in the 1970s and 1980s. FM radio, aided by the invention of ever smaller portable radios and inexpensive "Walkman" headts, dominates music programs, while AM has shifted to "talk" and news formats. Barely in existence 25 years ago, "talk radio," in which celebrities and experts from various fields answer listener "call-in" questions and offer their advice on various topics, has grown spectacularly in recent years. It has contributed to the comeback of AM radio. Both FM and AM radio have become increasingly specialized. Music formats, for instance, compri a variety of specializations -- the top five in 1991 being "country and western," "adult contemporary," "top 40," "religious" and "oldies."
In an era in which TV is clearly the glamour medium, the reach of radio is still awesome. Ninety-nine
percent of American houholds in 1999 had at least one radio; the average is five per houhold. Every day, radio reaches 80 percent of the U.S. population at one time or another. Revenues more than doubled from $8.4 billion in 1990 to more than $17 billion in 1999.
In 1998, the number of U.S. commercial radio stations had grown to 4,793 AM stations and 5,662FM stations. In addition, there are 1,460 public radio stations in the United States. Most of the stations are run by universities and public authorities for educational purpos and are financed by public and/or private funds, subscriptions and some underwriting. NPR (National Public Radio) was incorporated in February 1970 under the 1967 Public Broadcasting Act. NPR was created to provide leadership in national newsgathering and production and to act as a permanent nationwide interconnection of noncommercial stations.
4、Newspaper
The first U.S. newspaper, Publick
Occurrences: Both Foreign and
Domestick, first published on September
25, 1690 lasted only one day before it
was suppresd by British colonial
authorities. Other newspapers quickly
清明节调休sprang up, however, and by 1730, the
colonial press had gained sufficient
stature to riously challenge British
governors. Historians consider the birth
of America's free-press tradition to have
begun with the 1734 trial of John Peter
Zenger for ditious libel. After the
Revolutionary War (1775-1783), this
黄晓明和秦岚
concept found a home in the Bill of Rights, the first ten amendments to the U.S. Constitution. The First Amendment states: "Congress shall make abridging the freedom of speech or of " The 14 words made it possible for a free press to develop over the next two centuries as one of America's strongest watchdogs over government actions and protectors of individual rights. In fact, one of America's greatest political journalists was one of its first, Thomas Paine. Paine's stirring writings urging independence made him the most persuasive "media" figure of the American Revolution against Britain in 1776.
By the early 1800s, the United States had entered a period of swift technological progress that marked the real beginning of the "modern media." The inventions of the steamship, the railroad and telegraph brought communications out of the age of windpower and hors. The high-speed printing press was developed, driving down the cost of printing. Expansion of the educational system taught more Americans to read. Publishers realized that a profitable future belonged to cheap newspapers with large readerships and incread advertising. The press went from a small upper class readership to mass readership in just a few years. It was a time that shaped a breed of editors who t the standard for generations of American
