Farnsworth won the lawsuit against Zworykin and RCA over who invented the kinescope and the iconoscope. Thus, he’s known as

“the father of television.”

RCA now had to pay Farnsworth royalties to license his patents Sarnoff said of RCA that it was determined “to collect patent royalties, not pay

them.”

Television started broadcasting in 1939 World War II brought everything to a halt

PHILO FARNSWORTH

HISTORY OF TELEVISIONTelevision had been in development since the ’20s and there were experimental broadcasts in the

’30s. TV was introduced to the public at the 1939 New York World’s Fair, but development stalled during WWII. David Sarnoff, the head of RCA, and William Paley, the head of CBS, became instrumental in the growth of the television industry

The fifties became the golden age of television. In the fifties, more TV sets (70 million) were sold than children born (40 million).

In 1952 there were 108 TV stations. Ten years later there were 541. Today there are about 1,600 stations in the U.S.

Early programming included news, sports, game shows, sitcoms, children’s programming, variety shows and dramas. Most programming was live. Videotape was also introduced late in the decade.

The big three networks – ABC, CBS and NBC – dominated programming. On any given night more than 90 percent of viewers were watching one of the big three.

The first issue of TV Guide appeared April 3, 1953, at the cost of 15 cents. The sixties brought significant changes to the television landscape. Television journalism came of age thanks to several significant events in American and

broadcasting history. Broadcasting using satellite technology gave news organizations the ability to go “live”

from almost anywhere in the world. President Richard Nixon’s trip to China was televised live by all three networks in 1972.

•Cable television began to dramatically change the landscape of the industry. No longer just a “relay” service, cable operators began to offer alternative programming. In 1980 cable penetration stood at 20 percent. By the end of the decade, 60 percent of American homes received cable.

In 1995 the WB and UPN began offering primetime programming. Thanks to deregulation and the repeal of financial syndication rules, the traditional broadcast networks, while still losing audience share, regained their status as powerful television influences.

News programming became a constant presence and programming source. Entertainment programmers continued to push the envelope.

In 1996, the Telecommunications Act eliminated cable-rate regulation and allowed telco-cable competition.

Corporate mergers continue to reduce the number of “voices” heard in the television marketplace.

Digital television (“high def”) becomes more prevalent. Reality programming becomes TV's favorite programming genre. TV programming becomes available through the internet, Ipods, cell phones, etc.

TELEVISION AND SCIENCE

Television plays a critical role in the public’s understanding of new developments in science. Once they leave formal education, most Americans rely on television to keep them informed about science and technology. An important case in point is the genetic modification of foods, which has been touted as having the potential to increase food yield, enhance the nutritional value of foodstuffs and decrease the use of pesticides in agricultural practice. Yet despite the fact that concerns have been raised about the potentially harmful effects of genetically modified food on human health and the environment, the American public to a great degree remains unaware of the scope and extent of the products of this technology.

ROLE IN EDUCATION Television has been given considerable importance in many countries as a source

and tool of teaching. The success stories of using television for education in many countries has negated

the concept that television is basically on entertainment oriented medium and it is hostile to thoughts

Television is adaptable and can follow different approaches when used in different educational situations

Television can be attached with school curriculum and time tables The role of television is neither fixed nor easily tangible and measured

Educational Programming

MASS MEDIUM STAGE

In 1948, only 1 percent of American households had a TV set.

By the early 1960s, more than 90 percent of all homes had a TV.

COMMUNICATION Importance of television to communicate ideas, information, skills and attitude has

been affirmed by researches. You should attempt to study various report published to educational television in different countries in different situations.

In other words director of BBC “next to home and school I believer television to have a more profound influence on human race then any other medium of communication”

If media is to work as an effective teaching tool then certainly it is helping hand towards, achieving the aim and objectives of education

Media is an agent of boost cultural economic and social development activity
