The telephone is an all purpose tool. It is used in the home, business and in education. It is a source of entertainment and a vital resource to the illiterate as well as the academic elite. When the telephone was first introduced it could only be afforded by the rich as the materials needed for connection were very expensive . Alexander Graham's wish was to reduce the expense of materials so that the poorest man cannot afford to be without this telephone. The telephone was promoted on the grounds that it would increase wealth, employment and improved means of communication. The invention of the telephone lead to development of city centers, office buildings and the concept of an urban worker society.

The telephone changed the world by making it easy for people from anywhere in the world to contact others quickly. You can live in New York and call someone in California.
