If we go for television sets with cathode ray tubes, then the credit goes to a German radio and television apparatus company Telefunken
, which was founded in Berlin in 1903. The TV Sets were first manufactured by Telefunken in Germany in 1934. But if we remove the term cathode ray tubes, then the TV sets consisting of a "neon tube behind a mechanically spinning disk" were sold by Baird Television Development Company
in the UK in 1928. The cathode ray tube TV Sets were later made in France in 1936 and in Britain in 1936.
The television set frequently being used after 1970 when the availability of video cassettes, laserdiscs were available. There are many types of displaying technologies being used in Television like Disk, Cathode Ray Tube (CRT), Digital Light Processing (DLP), Plasma Display, Liquid Crystal Display (LCD) and Organic Light Emitting Diode (OLED). The first LCD TVs were introduced in 1988 with a B&W screen that could not display the full NTSC resolution of 480 lines. In the 1990s, three-line digital comb filters appeared on high-end TVs.
The Invention credit of TV sets goes to John Logie Baird
who was a Scottish engineer and inventor of the world's first practical, publicly demonstrated television system, and also the world's first fully electronic colour television tube. In 1927, Baird transmitted the world'sfirst long-distance television pictures to the Central Hotel at Glasgow Central Station from London over 438 miles. First transatlantic television transmission was achieved by the Baird Television Development Company in 1928. The development of television was the result of work by many inventors and Baird was a pioneer among them as he made a major advance in the field. According to many historians, Baird was the first to produce a live, moving, grayscale television image from reflected light. Baird achieved this by obtaining a better photoelectric cell and improving the signal conditioning from the photocell and the video amplifier while others failed to do so.
In the BBC's list of the 100 Greatest Britons in 2002, Baird was ranked number 44 after a UK-wide vote. He was inducted into the Scottish Engineering Hall of Fame in 2015 and was earlier named as one of the 10 greatest Scottish scientists in history.
