Since 1980 there have been four major developments in TV. The first is video, which has given 1 the power to control what they watch and when they watch it. These days, fifty percent of homes have a VCR (video-cassette recorder) and millions more are being sold every year. The second is satellite TV. Thanks to DBS (2), dozens of new channels are now 3 to anyone who buys a receiving “dish”.
The third development is cable－a system of hi-tech 4, which provides even more channels. But not only that, cable also makes 5 possible for you to communicate through your TV.
Fourthly, there’s HDTV (high definition television), which now offers a much 6 and more realistic picture than was possible even a few years ago.
So more channels, more choice, more clarity (清晰). What is there left for 7 to achieve in the future? The answer to that is two-way 8. Modern technology means that 21st century televisions will be linked to computer data-banks. This way. Views will be able to ask questions about what they’re watching and the answers will appear on their 9. This idea is called “hyper-media” and it’s still at an early 10. But then, as we’ve just seen, TV had come a very long way in a very short time. The hyper0media revolution could happen sooner than any many people think.
