Cultural Notes1.The Internet:an international computer network for the exchange of information. It wasoriginally used mainly in the academic and military worlds but has since become available to the large and increasing number of people with personal computers. Other services, e.g. the World Wide Web, are available through it.The Internet is changing our lives and a parallel universe is rapidly emerging online. Today there is scarcely an aspect of our life that isn’t being upended by the torrent of information available on the hundreds of millions of sites crowding the Internet, not to mention its saving companies billions of dollars in producing goods and serving the needs of their customers.Nothing like it has been seen since the beginning of the Industrial Revolution, when power-driven machines began producing more in a day than men could turn out in nearly a year. The Internet and e-commerce are viewed as a global megatrend along the lines of the printing press, the telephone, the computer and the electricity.You would be hard pressed to name something that isn’t available on the Internet.Consider: books, health care, movie tickets, baby clothes, stocks, real estate, toys and airline tickets. American kids today are so computer savvy that it virtually ensures the United States will remain the unchallenged leader in cyberspace for the foreseeable future. Most kids use computers to play games and have email chats with friends.What’s clear is that, whatever we like it or not, the Internet is an ever-growing part of our lives and there is no turning back.2.NBC (the National Broadcasting Company):the first of the original three US nationalbroadcasting companies. It was established in 1926 by Radio Corporation of America as two groups of radio stations. The first NBC television channel opened in 1940. The company is now owned by General Electric.
