Unit 4 Lesson 2 - Changes in Communication and Transportation Lesson Objective:  In this lesson, the student will analyze how the development of communication and  transportation inventions shaped the migration of the American people from rural to urban areas. The Communication Revolution Telegraph The communication revolution of the 1800's began early in the century with the invention of the telegraph by  Joseph Henry, which was made workable by Samuel F. B. Morse. Morse also developed a standardized code to  use with his device now called Morse Code. Just before the Civil War the first telegraph line to cross the continent  was completed by the Western Union Company.  Cyrus Field supervised the laying of the first telegraph line across the Atlantic Ocean in 1866, linking the United  States with Great Britain and the rest of Europe. People began to expect to learn about world and national events  within 24 hours, something that had never been accomplished before. Business began using the telegraph to  communicate with associates as well as everyday Americans sending personal telegrams. Telephone Even more significant than the telegraph was the invention of the telephone by  Alexander Graham Bell . Bell  entered his invention in the 1876 Philadelphia Centennial Exposition where it received worldwide attention. Within  ten years the American Telephone and Telegraph Company was established and the telephone soon became very  popular. Telephone poles began to change the landscape of both cities and rural areas.  The first switchboard was located in Connecticut and had approximately 20 customers. Within two years there  were over 50,000 telephones and by the turn of the century there were nearly two million. By 1915 the  transcontinental line was in service from New York to California. People could now talk across the country
