【題目】Television is one of the greatest technological inventions of the 20 century. A Scottish man called John Logie Baird invented it. Inventors in the USA and Europe were working on electronic television systems but Baird used a mechanical(機(jī)械的) system. In 1925, he was able to send the first black and white picture—of the head of a doll—from one end of his flat to the other. He then used a local office boy, not the doll, and this teenager was the first person ever to appear on TV.

In January 1926, Baird invited scientists to his flat and showed them his invention. He called it a “televisor”. Later that year, Baird started the world’s first TV station and gave it the name 2TV. In 1927, he sent images 730 kilometres from London to Glasgow using telephone cables(電纜). A year later, his company sent the first transatlantic(大西洋彼岸的) TV images from London to New York. Baird made the first television programmes for the BBC in 1929. These programmes had sound, not just pictures.

However, Baird's system was very limited and basic( 基本的). A totally electronic American system was more popular and practical. The inventor of this electronic system was an American, Philo Farnsworth. In 1936, the BBC started using Farnsworth's system because the picture was better than Baird’s.

More and more people had televisions after the Second World War. Colour TV began in the USA in the 1940s but only a small number of people had colour televisions in their houses. They were very expensive. In Britain and the USA, the first regular(有規(guī)律的) colour TV programmes only began in1967.

Now in the 21 century, we have digital television. TV has changed a lot since the face of a boy appeared on TV in John Logie Bairds flat.
