Zworykin's discovery caught the attention of David Scarnoff, the Vice President of the Radio Corporation of America (RCA)
At the Worlds Fair in New York City, Scarnoff presented this new technology to the public.
The CBS colour system did not work on older television sets, so by 1953, RCA developed their own all-electronic colour system.
General Information
Television... through the ages
Future of Television
, a Russian experimenter, was born in Murom, Russia, in 1889.
He went to the U.S.A. in 1919 and got a job at the Westinghouse Research Lab in Pennsylvania.
His work involved developement of radio tubes and photocells, and he experimented with television.
He called it a "
In January 1929, Sacrnoff made Zworykin the director of RCA's electronic Research Lab.
Zworykin is sometimes considered the
Father of Television
But meanwhile...
Philo Farnsworth
He was born in Utah in 1906, was always interested in technology and the concept of televison.
"A boy with a vision"
When he was 14, he had a simple idea of transmitting light line by line electronically, which is the foundation of modern day television
He continued to experiment with it, and by Summer 1927, applied for a patent for his electronic TV camera tube, which he called
image dissector
Farnsworth challeneged this claim, and won.
Now they got to work on improving their TV system
The FCC permitted satellites to be used to broadcast TV signals.
Soon after, RCA's National Broadcasting Company (NBC), began a regular schedule for TV programing,
Columbia Broadcasting System (CBC) and the American Broadcasting Company (ABC) started their own schedules after.
By 1940, only 5,000 sets were sold, but the U.S.A's entry to the world war stopped TV manufacture and programming.
Colour TV
He displayed the colour system before the FCC in 1941, and after seeing the demonstration, the public became excited for it.
At first sales were low, but by 1960's its caught on, and priced began to drop.
Sony introduced Betamax - a Home Video Recording System for more TV flexibility.
In Mahoney City, Pennsylvania, the signal strength of the TV networks were very low, so John Walson, an owner of an appliance store, set up an antenna on a utility pole.
He ran cable to his customers' homes and charged them $100 for installation and $2 a month for cable.
This is how Community Antenna Television (CATV) was born
That September, HBO (Home Box Office) broadcasted the championship fight between Muhammad Ali and Joe Frazier, live from Manila by satellite.
It was a huge success, and soon other cable channels used satellite as well.
Internet Television
Flat Screen TVs
As digital TV arrived in 1994, LCD (Liquid Crystal Display) and plasma sets became popular.
Cable became fee-based, and there was more variety
The civil rights movements in the 1960s and '70s helped shows become more diverse
Questions arose:
Should it be legal? was is violating shows' copyrights?
If users skip advertisements, would adversiters get less revenue?
U.S.A. supreme court ruled it as legal.
The television service broadcasted over the internet first with ABC's "World News Now".
Without television, ...
In the future, consumers may want to get rid of the remote control all together...
Can't always find your remote? Find it annoying to depend on it?
