Who Started the idea of creating the machine "Walkman"?

Akio Morita, chairman of Sony, was annoyed because his children constantly played loud music. He told his company engineers to devise some machine to make the music can only be heard by the user. They did, and the Walkman was born. This totally changed the way we listen to music. Morita personally insisted on using the name" Walkman" for the new machine. His advisers said the phrase meant nothing in English. But he knew it was easy to pronounce the word in nearly every language. So people all over the world will remember the name of this product. It was also short, catching and summed up the importance of the new device!
   Now the personal stereo is used by everyone. There are new designs such as CD Walkmans, recording Walkmans, etc. As size, weight and cost get smaller, quality gets bigger.
   Socially, however, the Walkman habit may not be so good. By playing their personal stereos at full volume in small spaces, listeners may disturb others. The repeated loud beat can also be annoying. That is why in London’s Underground Railway System there are signs saying, "Keep Your Personal Walkman Personal." Furthermore, drivers listening to Walkmans may sometimes cause road accidents to happen. And the rise in hearing problems is often blamed on their misuse.
   There is no doubt that modem society has a love-hate relationship with the Walkman. Yet even criticism proves how popular the Walkman has become. Rather like the television or the computer, it is hard to imagine how we ever lived without them.
