History of Television

This set covers the history of television.
What is television?
An electronic system of transmitting images and sound over wire or through space by an apparatus that converts light and sound into electrical waves and reconverts them into visible light rays and audible sound. The etymology of the word has mixed Latin and Greek origins. It combines the Greek word for "at a distance" with the Latin word "to see."
When was the era of Mechanical Television?
Before 1935.
Who is Guglielmo Marconi?
An Italian inventor known for his pioneering work on long distance radio transmission. He experimented in sending messages over great distances without wires. In 1895, Marconi sent the first successful wireless transmission. This sparked interest in others trying to find ways to send sound and images as well.
What is RCA?
The Radio Corporation of America (RCA) was formed in 1919 as a trust to oversee early radio companies. Later, this company branched into the emerging technology of television.
Who is Philo T. Farnsworth?
Electronic television pioneer. At age 14, had a vision of electronic TV scanning while plowing fields in 1921. In September 1927, Farnsworth transmits a straight line via his electronic CRT system.
Who is John Logie Baird?
A Scottish inventor who built a mechanical TV system. Responsible for electrically transmitting the first TV pictures in 1925. In 1926, he gave the world's first public demonstration of a mechanical television apparatus to approximately 40 members of the Royal Institution at his laboratory on Frith Street.
Who is Vladimir K. Zworykin?
In November 1929, at a convention of radio engineers in Pittsburgh, Zworykin demonstrated a television receiver containing his "kinescope," a cathode-ray tube. Zworykin demonstrated his all-electronic television system a full 10 years before it was introduced to the public at the 1939 New York World's Fair. In attendance was David Sarnoff, President of RCA. He was greatly impressed by the television presentation and decided to hire Zworykin to develop his TV system for RCA.
Who is David Sarnoff?
Television marketer and executive. Built one of the first commercial television stations in 1932 with transmitting facilities in the Empire State Building. Sarnoff didn't invent television but it was his historic meeting with engineer Zworykin that set the stage for RCA's success at perfecting electronic television transmission and reception.
What is the difference between mechanical and electronic television?
Mechanical TV was easier to invent and adopted earlier but electronic television had a superior picture and was eventually adopted as the standard for the emerging medium.
When was the birth of television?
The time period after WW II is considered the last and final birth of television. Families had accumulated savings during the war years and were eager to purchase homes, cars and other luxuries denied to them during the war. The explosion of TV sets into the American marketplace occurred in 1948-49. The post-war sales boom for England followed a few years later.
When was the birth of color television?
Color TV became widespread in the early 1950's. In 1954, RCA placed its first all-electronic color set on the market.
