It was the first demonstration of a television system that could scan and display live moving images with tonal graduation.[3]
He demonstrated the world's first colour transmission on 3 July 1928, using scanning discs at the transmitting and receiving ends with three spirals of apertures, each spiral with a filter of a different primary colour; and three light sources at the receiving end, with a commutator to alternate their illumination.[28][29] That same year he also demonstrated stereoscopic television.[30]
Broadcasting
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.[31] This transmission was Baird's response to a 225-mile, long-distance telecast between stations of AT&T Bell Labs.[32] The Bell stations were in New York and Washington, DC.
The earlier telecast took place in April 1927, a month before Baird's demonstration.[20]
Baird set up the Baird Television Development Company Ltd, which in 1928 made the first transatlantic television transmission, from London to Hartsdale, New York, and in 1929 the first television programmes officially transmitted by the BBC.
In November 1929, Baird and Bernard Natan established France's first television company, Télévision-Baird-Natan.[33] Broadcast on the BBC on 14 July 1930, The Man with the Flower in His Mouth was the first drama shown on UK television.[34] The BBC transmitted Baird's first live outside broadcast with the televising of The Derby in 1931.[35][36] He demonstrated a theatre television system, with a screen two feet by five feet (60 cm by 150 cm), in 1930 at the London Coliseum, Berlin, Paris, and Stockholm.[37] By 1939 he had improved his theatre projection to televise a boxing match on a screen 15 ft (4.6 m) by 12 ft (3.7 m).[38]
From 1929 to 1935, the BBC transmitters were used to broadcast television programmes using the 30-line Baird system, and from 1932 to 1935 the BBC also produced the programmes in their own studio, first at Broadcasting House and then later at 16 Portland Place.[39] In addition, from 1933 Baird and the Baird Company were producing and broadcasting a small number of television programmes independent of the BBC from Baird's studios and transmitter at the Crystal Palace in south London.[40]
On 2 November 1936, from Alexandra Palace located on the high ground of the north London ridge, the BBC began alternating Baird 240-line transmissions with EMI's electronic scanning system, which had recently been improved to 405-lines after a merger with Marconi.
Edinburgh: National Museums of Scotland Publishing, 2006. Several months prior to this trip, Baird had met Margaret Albu, a concert pianist from South Africa. His landlord, Mr Tree, asked him to quit his workshop and he moved to upstairs rooms in Soho, London, where he made a technical breakthrough. Paul Gottlieb Nipkow had invented this scanning system in 1884.[19] Television historian Albert Abramson calls Nipkow's patent "the master television patent".[20] Nipkow's work is important because Baird, followed by many others, chose to develop it into a broadcast medium.
From 1934-35, he improved the performance of Farnsworth’s Image Dissector camera from 440 to 700 lines. Although there was a 19-year age difference they fell in love and while in New York Baird proposed marriage to her. He also gave the first demonstration of both colour and stereoscopic television.
In 1929, the German post office gave him the facilities to develop an experimental television service based on his mechanical system, the only one operable at the time.
Soon after, he founded the Baird Television Development Company Ltd.

The Baird company used the Farnsworth tubes instead to scan cinefilm, in which capacity they proved serviceable though prone to drop-outs and other problems. 69

America may have been slow to the draw, but it came out with every gun blazing, with a little help from its own regulatory bodies - and the Third Reich.
When Neil Armstrong set foot on the moon, the camera used to transmit the live pictures was based on Baird’s Field Sequential Colour System, because this was the best and most reliable available.
Baird’s true story has been obscured for a long time. Nevertheless, a BBC committee of inquiry in 1935 prompted a side-by-side trial between Marconi-EMI's all-electronic television system, which worked on 405 lines to Baird's 240. [7]

The screen displayed half tones - black and white, and shades of grey - using a method he had patented three years before.
He accomplished this by improving the signal conditioning from the cell, through temperature optimisation (cooling) and his own custom-designed video amplifier.[23]
First public demonstrations
Baird gave the first public demonstration of moving silhouette images by television at Selfridges department store in London in a three-week series of demonstrations beginning on 25 March 1925.[24]
On 26 January 1926, Baird gave the first public demonstration of true television images for members of the Royal Institution and a reporter from The Times in his laboratory at 22 Frith Street in the Soho district of London, where Bar Italia is now located.[5][25][26][27] Baird initially used a scan rate of 5 pictures per second, improving this to 12.5 pictures per second c.1927.
He also used Farnsworth’s ideas to build bigger and better TV tubes.
