Television is good invention

Mechanical television Facsimile transmission systems pioneered methods of mechanically scanning graphics in the early 19th century. The Scottish inventor Alexander Bain introduced the facsimile machine between and The English physicist Frederick Bakewell demonstrated a working laboratory version in

Television is good invention

This is the best invention because it is big. John Logie Baird demonstrated his Televisor system to the public in March inside Selfridges, a London department store.

Two years later in he showed the "phonovision" system of recording TV. Designs and patents for electro-mechanical television systems had been proposed as early as by German student Paul Gottlieb Nipkow but never built. It was this invention, the Nipkow disc, that Baird used for his televisor.

An all-electronic moving-image television system somewhat similar to that used today was invented and demonstrated in by Philo Farnsworth. In the same year, the BBC in London began the first television broadcasts available to the public. Television broadcasts were halted in at the start of World War II, the same year that RCA began their broadcasts in the US, representing the start of publicly available television in North America.

Inscientists at the laboratories of the Radio Corporation of America RCA developed the Image Orthocon Tube, a far more sensitive light sensor than previous cameras used. The new tube made production far easier and effective. John Logie Baird August 13, - June 14, a Scottish engineer invented the TV on the 26th January and it was demonstrated a year later in the "phonovision" system of recording TV.

InBaird then demonstrated the first color tv: Television has been around since It was then that John Logie Baird demonstrated the first television system to the public. His system was an electro-mechanical device that used a spinning disc to create a moving image. It was used for the very first public broadcasts in by the BBC in London.

Farnsworth carried out his first demonstration of another electro-mechanical system in but two years later, he had eliminated the moving parts and therefore is credited with the first person to produce a fully electronic system. Some sources say Zworykin did the same, around for RCA in New York -- he was on the east coast, and Farnsworth was on the west coast, but both were experimenting with electronic, rather than mechanical TV.

Baird and Farnsworth worked together in a bid to use their new system but the BBC chose a competitive system. This was partly due to additional development work by Farnsworth but legal challenges to patents were the major factor in the delay. American televisions did not really take off in availability and popularity till after World War II has ended, at which time, a number of stations in most major cities went on the air.

John Logie Baird showed a working television system to the public in His public demonstration subsequently took place in Selfridges, a department store in London England, during March Paul Nipkow, a German inventor patented the disc in as a means to capture an image for telegraphic transmission.

His invention was largely ignored and Nipkow never built the disc himself. The patent expired in and Baird adopted the device for use with moving images.

InBaird demonstrated the first color television.

Like his monochrome television, it used rotating discs to build the image. The three discs added red, green and blue light together to create a full-color image. Although cumbersome, it demonstrated the principles of color television that have remained in use to this day.

On the other side of the Atlantic, several inventors were working on the same idea. One was Charles Francis Jenkins, who put a number of mechanical television stations on the air in the eastern United States in the mids.

Also, there was Philo Farnsworth, a west-coast inventor whose first demonstration of television was in During the same time period, Vladimir Zworykin, a Russian engineer working for Westinghouse in Pittsburgh, was working on television.However, Farnsworth's invention, which scanned images with a beam of electrons, is the direct ancestor of modern television.

The first image he transmitted on it was a simple line.

Television is seen as something good or evil depending on the people and circumstances. Some parents consider television to be one of the worse technological inventions of all times, while others find it to be one of the most beneficial inventions ever created.
