Television was developed in the 1920s and 1930s but was introduced to the public at the 1939 New York World's Fair. Philo Farnsworth invented key components of early television like the kinescope and iconoscope and is considered the father of television. During the 1950s, television ownership rapidly expanded and the medium became a dominant form of entertainment and news delivery in American homes. Today, television continues to evolve with new technologies and remains an important source of information, entertainment, and education for many people.

6. HISTORY OF TELEVISION
Television 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

7.  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.

televised live by all three networks in 1972.

8. •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.

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.

9. 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.
