How television was invented

Television owes origins to many inventors. But it was the single-minded determination of an amateur inventor, John Logier Baird that led the first live television broadcast.

Born in Scotland in 1888 and educated in Glasgow, John Logier Baird earned a living a razor-blade salesman. In the 1890s Galileo Marconi showed that sound could sent by radio waves. Baird became convinced that a similar system could transmit a picture. He spent most of spare time working on his ideas in his tiny workshop without Commercial support. He to use his earnings to continue his research.

In 1924, Baird successfully transmitted the general outline of a figure over more 3 metres. He continued to experiment and October 25, 1925 transmitted a recognisable image of a doll. He ran to the office on the ground floor and persuaded one of the office boys to come upstairs. boy became the first living image transmitted by television. Overnight, Baird became famous and the money he needed to continue his research was at made available. In 1927 he made a transmission from London to Glasgow and in1928 he made from London to New York. He continued experimenting spent his last years exploring the possibility of colour television.
