[单项选择]The name "Television" comes from the Greek word "tele" meaning "far" and the Latin word "videre" meaning "to see". Thus television means "seeing far".
Television brings the world into home in sight and sound. Nowadays there are few families in the big cities that do not have TV sets. Entertaining us with singing, dancing and acting, television helps us to live happily.
Experiments leading to modem television took place more than a hundred years ago. John Baird, a British inventor, found a way to send pictures by wireless. This happened in the year 1925 and it was the beginning of television. It took another thirty years for television to be an industry.
Although television was developed for broadcasting, many important uses have been found that have nothing tO do with it.
