雅思阅读真题+题目+答案：The Invention of Television

The question “Who invented television?” is simple enough, but the answer is surprisingly controversial. No one person was responsible for producing what we think of as television today and the credit is due to various inventors.

The Scotsman, John Logie Baird, is considered by many to be the inventor of television. He showed early signs of his inventing ingenuity by setting up a telephone exchange to connect his house to those of his friends near by. His first interest in television came in 1903, after he read a German book on the photoelectric properties of selenium. In 1873, this element was discovered to have the capacity to generate a current based on the amount of light applied to it. Working initially in Hastings, England, Baird famously created an apparatus using an old hatbox he bought in a used goods store, a pair of scissors, some needles, some bicycle light lenses and an old tea chest. Baird also used a Nipkow disk, created by German inventor, Paul Nipkow, and a lot of his work was based on the previous work by German, Arthur Korn. In February 1924, Baird demonstrated moving silhouette images on a ‘television’. Later that year, after nearly destroying the house and nearly killing himself with an electric shock, Baird moved to London, where he gave the first public display of his invention. On 2 October 1925, Baird used an office assistant, William Taynton, to move for his transmitted pictures, and Taynton became the first person to be televised moving and in full tonal range. Baird is also later credited with demonstrating the first images on colour television, on 3rd July 1928, although the credit for being the inventor of colour television is again disputed. Another first for Baird was transmitting the first television pictures across the Atlantic in 1928. Although Baird was well known for his invention, he also became famous for refusing an offer of £100,000 for the shares in his company, which was an enormous sum at that time. Baird famously said that he would not be able to sleep at night, knowing he had that much money.

Philo Farnsworth successfully demonstrated electronic television in San Francisco, in 1927, using a different system. Farnsworth realised that a picture could be dissected by a simple television camera into a series of lines of electricity. The lines would be transmitted so quickly that the eyes would merge the lines. Then, an image dissector, which Farnsworth created, would change those lines back into a picture. The Russian inventor, Vladimir Zworykin, built on this work and it was Zworykin’s designs that were eventually used by the BBC in the UK to replace Baird’s system.
