The Future of American TelevisionAlong with the ideological liberation and the technological progress, broadcast stations in all U. S. markets have developed rapidly.With the development of broadcast technology, American TV delivery systems experienced four stages.The development of TV transmission technologyFirst stage is over-air stations.In the primary stages of the period,television is conceived of as radio with pictures.They radio people.The television system they built to send signals to homes just like radio.Until a newsman named Edward R.Murrow opened his “See It Now”with live picture from cameras on the Atlantic and Pacific oceans,people marveled.The next is cable systems.Now two-thirds of U.S. households receive television via wire.The cable television industry has grown from independent small-town community antenna systems into a well-heeled,consolidated industy.Now,cable companies and phone company are in a race to replace their wires to deliver more data and sharper pictures.But the competition often results in neither.The best way for cable and phone companies is mutual cooperation.The third stage is satellite-direct.For more than a decade Hubbard poured millions of dollars into his vision for direct-broadcast satellite delivery-DBS for short.In 1994 Stanley Hubbard and a Genaral Motors subsidiary,DirecTV,launched Digital Satellite Service.Since then,the satellite=direct services have begun operation all over the world.The next stage is interactive television. Traditional TV is broadcasting form,but the interactive television is a vod form and users can interact with the television. Content changesNot only TV delivery systems changed,but also the contend of news program have changed.The television netxorks began news programs in 1947, respectively is CBS with “Douglas Edwards and the News”and NBC with John Cameron Swayze’s “Camel News Caravan”.The networks built up their own reporters and abandoned the photogenic but predictable newsreel coverage of events like beauty contests and ship launchings.Then prime-time magazine programs,like “60 Minutes”and”20/20” had appeared and became popular.After that 24-hour television news and local newappeared.From the televiewer to usersAll of these changes in american TV industry means that whether the television equipment maneuverability or the appreciation of TV programs both pay more and more attention to the needs of users.Although since the advent of television,it is more and more advanced,there are still a shortcoming that restricts the TV further breakthrough.It is lack of interactivity.Television is a one-way pair of much broadcast forms. The audience can't interact with the news reporter or TV programs directly.Although there are interactive program which the audience can interactive by SMS,it interaction worse and cannot receive feedback rapidly.The Internet is a best interactive ers can get the feedback informations repidly.If the traditional television combine with internet, the new television will both have the advantage of rich sources and the advantage of interactive.The televiewer are turned into the users.The future of televisionHow to combine the traditional TV and Internet is a big challenge.There are impediments.For one thing,more than simply plugging in was required.For people receiving over-air or satellite television signals,a separate cable or telephone line needed to be installed for e-messageing and web downloading,Older cable systems couldn’t handle two-way messages.Too,a full-fledged hybrid of cable television technology and still-temperamental web technology had practical problems.The combine of traditional TV and Internet still need further study.Now that the American TV markets fall into two categories, one of them is traditional television, the other is Web television. At present the traditional television still occupy most of the market.Engineers,broadcast leaders and the Federal Communications Commission structured television delivery much like video.The original over-air system is now supplemented with cable and satellite-direct delivery.The traditional American television consists mainly of cable and satellite television.In America, only CATV users will have the nearly 70 million by 2010. How large the user base are! American wireless television is mainly satellite TV.By 2004 the leading DBS company,Direc TV,claimed 11.9 million subscribers,more than any cable operator except Comcast.Dallas became the first major city with more satellite than cable subscribers in 2003.Elsewhere,DBS growth also was out-flanking cable growth.Although, the traditional television still occupy most of the market at the present,the rapid development of interconnection network makes online video in the American market’s position are rising rapidly. A research found that due to the popularization of high-speed Internet connections and a large number of the video contents,there are about one in five Americans watching online video every day. The pell-mell impact of the web on older mass media portends special importance for television.These two media share so many qualities.Both television and web messages are visual,in motion,auditory an live.Not to be overlooked is that both are received by appliances that are widely available.Almost as soon as the web took root as a new mass medium,futurists saw television and the web melding into a single interactive medium. The media hybrid was dubbed interactive television and had numerous brand names,including Web TV.The definition of Web TV is that use the resource of CATV network broadband and set the Internet, multimedia, communication and so on many kinds of technology in one body to offer a variety of interactive services to household Internet TV users. Web television , also commonly referred to as Web TV , not to be confused with Internet television or Catch up TV , is an emerging genre of digital entertainment that is distinct from traditional broadcast television.On May 19,2010, in 2010 Google I/O conference Google released its latest products—Google TV. Google TV made the internet and television unifies in together. To become a new set of family entertainment system. The United States has decided to to complete halt of analog TV signals broadcast on February 17th, 2009. At that time they will thoroughly enter digital TV era. And now the United States has about 6,900 million television, it is distributed in 2000 million households around the nation. In the future they must use STB signal conversion to watch television programs. This also provides a good business opportunity for Web TV’s development.。
