Question

In which year John Logie- Baird invented the world’s first working television?
A) 1906
B) 1920
C) 1926
D) 1932

Answer 1

Hint: The invention of the television was a combined effort of many inventors in the 19th and early 20th century, but the groundwork was already laid in the 18th century.

Complete answer: John Logie-Birdie was a Scottish engineer, who performed the first of a working television system on October 2, 1925. He performed the test in his London lab, where he was successful in transmitting the first television picture with a grey image. When his experiment was successful he called Edward Taynton who became the first person to be televised in a full range. He wanted to show his achievements to the people worldwide and so went to the newspaper office to get his work published, but his work was eventually rejected and he was called a lunatic.
After getting his work rejected Baird was again able to garner enough attention from the media in January 1926 when he repeated his experiment of transmission for the Royal Institution and a Times reporter in his lab. He also modified his scan rate by 12 times. It was the first illustration where a television set was successful in broadcasting live moving images with clear tonal graduation. In January 1926 he in London gave a demonstration of the first working television system. He also went on to show the world's first coloured transmission in 1928, and in 1932 became the first person to successfully show the ultra short wave transmission.
Therefore, option C is the correct alternative of the lot.

Note: Baird’s electromechanical television system was eventually displaced by electronic television systems, Baird’s television invention earned him a prominent place in the history of the invention of television.
