      As the Internet becomes more popular, many older media (媒体) businesses are dying out. But

TV seems to be doing OK. In fact, it's doing better than OK. Though the Internet is popular in the

world, television continues to draw more and more people all over the world to many of its programs.

Hundreds of millions turn to TV to watch World Cup soccer,Olympic Games and Discoveries.

      In many places, increasing numbers of people can watch more TV than before. Ten years ago,

only 44% of British homes had satellite or cable TV(卫星或有线电视).Today, more than 93% do.

More importantly, recent studies show that people are spending more time watching TV. Surprisingly,

this is even true of young people between the ages of 8 and 18.Today's television industry has given so

many choices. As a result, people can watch more of the things they like 24 hours a day.

     The technology behind television has also improved. The big boxes that once filled living rooms are

gone. Today's TV screens are thinner and thinner, yet the pictures are better and better. TVs are also

moving from living rooms into kitchens and vehicles.

new ways. Many televisions can connect to the Internet and record programs. They also let people

watch two programs at the same time. Today the most modern television has been on the way of

development.

     The Internet is the main challenge (挑战) for television now. But TV industry has shown that

television will be important for years to come.
