The home computer industry has been growing rapidly in the United States in the last ten years. Computers used to be large, expensive machines that were very difficult to use. But scientists and technicians have been making them smaller and cheaper while at the same time they have been made easier to use. As a result, their popularity has been increasing as more people have been buying computers for their homes and businesses.
Computers have been designed to store information and compute problems that are difficult for human beings to work out. Some have voices that speak to their operators. Stores use computers to keep records of their inventories and to send bills to their customers. Offices use computers to copy letters, record business and keep in touch with other offices. People also use computers in their homes to keep track of the money they spend.
One important new use of computers is for entertainment. Many new games have been designed to be played on computers. People of all ages play these games. People also buy home computers to watch movies and listen to concerts at home. They have become very popular indeed.
