John Logie Baird demonstrated his Televisor system to the public in March 1925 inside Selfridges, a London department store. Two years later in 1927 he showed the "phonovision" system of recording TV.
Designs and patents for electro-mechanical television systems had been proposed as early as 1884 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 1929 by Philo Farnsworth.


In the same year, the BBC in London began the first television broadcasts available to the public. They used Baird's Televisor system which remained in use until 1936 when the BBC moved to an all electronic higher definition system. Television broadcasts were halted in 1939 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.
In 1946, scientists 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, 1888 - June 14, 1946) a Scottish engineer invented the TV on the 26th January 1926 and it was demonstrated a year later in 1927 the "phonovision" system of recording TV.

In 1927, Philo Farnsworth made the world's first working television. In 1928, Baird then demonstrated the first color tv :)
Television has been around since 1925. 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 1929 by the BBC in London.

Across the Atlantic, Philo Farnsworth was also working on similar systems, as was Vladimir Zworykin. Farnsworth carried out his first demonstration of another electro-mechanical system in 1927 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 1928 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.)

By the mid 1930s, the BBC had given up on Baird's system and replaced it with a fully electronic version. Baird and Farnsworth worked together in a bid to use their new system but the BBC chose a competitive system. The BBC first went on the air with regular programming in 1936 (the opening song was "Magic Rays of Light").

In America, scheduled public broadcasts did not start until 1939, at the New York World's Fair, where NBC debuted its WNBT-TV. 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 1925.
Baird was a Scottish engineer and inventor of the world's first working television system in Hastings, England, in 1923. His public demonstration subsequently took place in Selfridges, a department store in London England, during March 1925. The system was successful enough to become commercialized, and the BBC began the world's first regular television broadcasts in January 1929, using Baird's system.

Baird's "Televisor" was an electro-mechanical system and used a rotating disc called a Nipkow disc. Paul Nipkow, a German inventor patented the disc in 1885 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 1899 and Baird adopted the device for use with moving images.

In 1927, Baird transmitted a long-distance television signal over 438 miles (705 km) of telephone line between London and Glasgow; Baird transmitted the world's first long-distance television pictures to the Central Hotel at Glasgow Central Station.

In 1928, Baird 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 mid-1920s. Also, there was Philo Farnsworth, a west-coast inventor whose first demonstration of television was in 1927. Like Baird's system, it was electro-mechanical, but by 1929 he had eliminated the moving parts of his system to create the world's first fully electronic system.

Farnsworth's developments were adopted by The Radio Corporation of America, one of the major radio broadcasters in the US at the time (Better known as RCA), but commercial television broadcasts in the US were delayed because of legal battles over patents. It was in 1939 that RCA began the first commercial and public television broadcasts using Farnsworth's system.

During the same time period, Vladimir Zworykin, a Russian engineer working for Westinghouse in Pittsburgh, was working on television. He was granted several patents, but didn't quite reach a full working television system. However, in the 1930s he developed the "Iconoscope," a form of cathode ray tube to capture moving images electronically. This paved the way for better-quality image capture.

Since those pioneering years of the 1920s, the development of television has been rapid and consistent. The BBC adopted a fully electronic system of television in 1936 and Baird's system fell into disuse after that time.

The 1940s saw dramatic improvements in the sensitivity and quality of camera tubes. The 1950s marked the first color broadcasts in the US, while Britain and Europe began seeing television in color during the 1960s.
Further developments in the 1980s and 1990s introduced high definition television standards and flat screen televisions. In the 21st century we enjoy high-definition television on larger and brighter screens than ever before. Despite the advances, the principle of television today is still based firmly on the early work of Baird and Farnsworth.
