TV was one of the greatest inventions in the 20th century. Nowadays，nearly every household has at least one TV set.
Television came into being based on the inventions and discoveries of many scientists. On April 7，1927，the first public television programme was broadcast in the USA. The signals were received on a very small screen. It was only about the size of a business card. The pictures were reddish and not clear.
In the 1930s, bigger screens appeared with black-and-white pictures. However，a snowy picture was the best many TV viewers could hope for. Often, they could only get one station，and only when the weather conditions were good.
When World War Ⅱ(1939-1945)began，the development of TV stopped. There were a very small number of TV sets in the hands of the public. By 1945，there were fewer than 7,000 working TV sets in the USA. A TV set cost about half the price of a car at that time.
The period after World War Ⅱ is considered the final birth of television. Families saved money during the war years，and wanted to buy a lot of things after the war. TV sets were soon put onto the "must have" list. 1950-1959 was an exciting period for television. Colour televisions and remote controls came out during this time. By 1955，the cost of TV sets came down a lot. Instead of being equal to half the price of a car, they were now just equal to the cost of a new set of tires. That marks the beginning of the booming age of TV.

Sir Run Run Shaw, one of the pioneers (先锋)of the 20th century Chinese film industry, passed away at his home in Hong Kong at the age of 107.
Shaw was born in Ningbo, Zhejiang, China and raised in main land China, but received his education in American-run schools. At the age of 19, during his summer vacation, he followed his third elder brother Run Me Shaw to Singapore to start a film market and establish Shaw Organization. Following that, he developed a deep interest in the movie business. He and his brother founded the South Seas Film studio in 1930, which later became Shaw Studios. In 1967, he set up TVB (Television Broadcasts Ltd.) in Hong Kong, growing it into a multi-billion dollar TV empire(帝国) , one of the top 5 television producers in the world today .
In fact, the legendary man was regarded as “the most familiar stranger” by many Chinese. We know him through his donations to thousands of projects around the country, including the most famous one, “Shaw Building.”
“The ‘Shaw building’was a mark carved on our school days,” said Ma Nini, a 30-year-old editor who graduated from a university in the northeast China city of Harbin.
“No matter whether a library or a science hall, the ‘Shaw building' was always the most advanced and well-equipped one on campus,” said Ma.
Shaw was enthusiastic for charity and donated more than 10 billion HK dollars (about 1.29 billion U.S. dollars), with a large sum went to the support of education in China's mainland. Since 1985, Shaw donated 4.5 billion HK dollars for over 6,000 projects on the Chinese mainland -- over eighty percent of them related to education. In 1988, Shaw donated about 20 million yuan to build the village's Shaw Center, which includes a kindergarten, senior center. They are still in use now.
“I always go to the Shaw building on my campus to study. We never met before, but I am so grateful to the old man," said a college student surnamed Li from Tsinghua University who rushed to the village from the Ningbo Airport.
As Li paid his respects to the “most familiar stranger," he said that he would keep in mind a quote from Shaw: “Coming from people, my wealth(财富) should benefit (有益于)the people."
