Industrial technology began about 200 odd years ago with the development of power-driven machines, the growth of factories, and the mass production of goods. As the industrial technology advanced, it affected more and more aspects of man's life. For example, the development of the automobile influenced where people lived and worked and how they spent their leisure time. Radio and television changed entertainment habits, how the telephone revolutionized communication. Today, industrial technology helps man achieve goals that few men thought were at all possible 100 years ago. It gives him the means to conquer hunger and to cure or prevent many diseases. It allows him to transport any goods and passengers to any place on earth that they wanted. He can even leave the earth, soar through space, and eat food on the moon.
