With the start of BBC World Service Television, millions of viewers in Asia and America can now watch the Corporation's news coverage, as well as listen to it.  
And of course in Britain listeners and viewers can tune in to two BBC television channels, five BBC national radio services and dozens of local radio station. They are brought sport, comedy, drama, music, news and current affairs, education, religion, parliamentary coverage, children's programmes and films for an annual license fee of ￡83 per household.
It is a remarkable record, stretching back over 70 years - yet the BBC's future is now in doubt. The Corporation will survive as a publicly-funded broadcasting organization, at least for the time being, but its role, its size and its programmes are now the subject of a nation-wide debate in Britain.
The debate was launched by the Government, which invited anyone with an opinion of the BBC - including ordinary listeners and viewers - to say what was good or bad about the Corporation, and even whether they thought it was worth keeping. The reason for its inquiry is that the BBC's royal charter runs out in 1996 and it must decide whether to keep the organization as it is, or to make changes.
Defenders of the Corporation - of whom there are many - are fond of quoting the American slogan. If it ain't broke, don't fix it. The BBC ain't broke, they say, by which they mean it is not broken (as distinct from the word broke, meaning having no money), so why bother to change it?
Yet the BBC will have toks5u change, because the broadcasting world around it is changing. The commercial TV channels － ITV and Channel 4－ were required by the Thatcher Government's Broadcasting Act to become more commercial, competing with each other for advertisers, and cutting costs and jobs. But it is the arrival of new satellite channels - funded partly by advertising and partly by viewers' subscriptions - which will bring about the biggest changes in the long term.

You never see him, but they're with you every time you fly. They record where you are going, how fast you're traveling and whether everything on your airplane is functioning normally. Their ability to endure almost any disaster makes them seem like something out of a comic book. They're known as the black box.
　When planes fall from the sky, as a Yemeni airliner did on its way to Comoros Islands in the India ocean on June 30, 2009, the black box is the best bet for identifying what went wrong. So when a French submarine (潜水艇) detected the box's homing signal five days later, the discovery marked a huge step toward determining the cause of a tragedy in which 152 passengers were killed.
　In 1958, Australian scientist David Warren developed a flight-memory recorder that would track basic information like altitude and direction. That was the first mode for a black box, which became a requirement on all U.S. commercial flights by 1960. Early models often failed to withstand crashes, however, so in 1965 the box was completely redesigned and moved to the rear of the plane – the area least subject to impact – from its original position in the landing wells (起落架舱). The same year, the Federal Aviation Authority required that the boxes, which were never actually black, be painted orange or yellow to aid visibility.
　Modern airplanes have two black boxes: a voice recorder, which tracks pilots' conversations, and a flight-data recorder, which monitors fuel levels, engine noises and other operating functions that help investigators reconstruct the aircraft's final moments. Placed in an insulated (隔绝的) case and surrounded by a quarter-inch-thick panels of stainless steel, the boxes can stand massive force and temperatures up to 2,000℉. When submerged, they're also able to emit signals from depths of 20,000 ft. Experts believe the boxes from Air France Flight 447, which crashed near Brazil on June 1,2009, are in water nearly that deep, but statistics say they're still likely to turn up. In the approximately 20 deep-sea crashes over the past 30 years, only one plane's black boxes were never recovered.
