The Development of Television Technologies
The first moving-image television broadcasts were achieved in 1925 although earlier still-image transmissions had been achieved. The Russian-American scientist and inventor Dr. Vladimir Kosma Zworykin was awarded patents in 1923 and 1924 for the iconoscope camera tube and the kinescope picture tube respectively.1 These technologies would form the basis for the all electric television system, and in 1929 he was awarded his first patent for color television. John Logie Baird was able to demonstrate a successful transmission of a moving image in 1926, transmitting the image of a puppet and a human face to a television screen first from within the same room and then from outside of the room for his viewers, members of the Royal Institute in London, England.2 It was remarked at the time that it was unknown to what practical applications the technology could be put to. On February 8, 1928 Baird and his company were able to successful transmit a moving image across the Atlantic Ocean from his studio in London to a receiver in New York City.3 It was the following year when the first official broadcast of television was made by the British Broadcasting Company who had been working with Baird to develop successful broadcasting technologies and ones that would be made to private citizens owning television receivers.4 In the meantime, worldwide development of different television technologies had continued but television and television broadcasting remained primarily experimental until the late 1930s and 1940s. The National Broadcasting Company in the United States did not begin regular broadcasting until 1939 or 1940, and it was only in 1945 and 1946 that the British and Soviets began or resumed regular broadcasting, and by 1952 the BBC would be broadcasting from London to viewers in Paris.5 It would not be until 1952 that the first demonstration of a television broadcast was made within Thailand, and in less than three years Thailand would have its first broadcasting station.
