Submitted to: Mr. Bouzane Submitted by: Robbie Collins

It wouldn’t be fair to give only one person all the credit for inventing the first television. Philo T. Farnsworth, Paul Nipkow, Vladimir Zworykin, Charles Jenkins and John Baird are the five people who contributed to the first television.

The first television …

Contribute to the first TV.

Paul Nipkow developed a rotating disc technology to transmit pictures over wires in 1884 called the Nipkow disc. He was the first

person to discover the television scanning principle, in which light particles of an image are successfully analyzed and transmitted.

In the 1920’s, John logie Baird patented the idea of using arrays of transparent rods to transmit images for television. John Logie Baird based his inventeion

on Nipkow's scanning disc idea.

Philo Farnsworth developed a television s, and is best known for the first fully functional all-electronic image pickup device, the first image dissector , the first fully functional electronic television system with receiver and camera and he was the first person to show this to the public.

The first television had a tiny screen but as the years went by the screen got bigger and bigger, now we have 3d TV’s and in the future we might even have virtual Tv.

3D TV The future ….

In the 1930’s, the first real commercial TV became available and Sets were large pieces of equipment with about 12 inch screens. They cost about $400 to $500 and the average household income was about $1300 a year.

In the 1940’s the hype of TVs was pushed to the side because of WW1 and the production was put on stop.

Television through the years !

In the 1950’s, colour tv’s came in and remote’s were invented. By the end of the decade, a 21-inch black and white set was about $200 and the average 21-inch color set was almost $500.

In the 1960’s, by the end of the decade there were approximately 78 million television sets in homes across the United States; 200 million around the world.

In 1970, the average television was $400- $700. the first direct to broadcast satellite television was launched in 1978.

In the 1980’s, there became a growing number of television accessories, like the VCR and the Nintendo. And cable had a significant boom in the 80’s.

In the 1990’s, plasma and LED television was being experimented. Televisions now included picture in picture, timers and parental controls.

In the 2000’s, DVD players have token over theatre experience. At the beginning of the decade they were only in 7% of homes and in less then 10 years it has gone up to 80%. Less then 10 years later after the DVD players, they came out with HD DVD and Blu-ray. The tv goes online with the introduction to high speed internet and video streaming.

The television of the future could be a see-through panel which vanishes when you turn it off - carrying on the current trend for ever-thinner sets.

or it may be stretched out longer and even though can get internet on TV’s now they will have a more advanced technology.
