**Morse Code** Samuel Morse invented Morse Code in 1838 in England. Morse Code was a new and effective way to communicate using the telegraph. He introduced a letters code currently known as American Morse. **Alexander Graham Bell and the Telephone** Throughout Alexander Graham Bell's life, he had been in the education of the deaf. This interest lead him to invent a microscope and in 1876 his "electrical speech machine", which is now called a telephone. Success with telephone came from trying to improve the telegraph. The telegraph was limited to receiving and sending one message at a time. He was able to transmit multiple messages over the same time. Since Bell's death in 1922, the telecommunication industry has undergone an amazing revolution. Now deaf can use the telephone. This invention paved way for the modern day internet. **The First Telephone Company** The first company to connect the phone lines from one side of the country to another was AT&T in 1914. They placed wires along 3400 miles. As the voice signal traveled farther and farther it began to weaken. In 1877 construction of the first telephone line was completed. It extended from Boston to Somerville Massachusetts. By th end of 1880 there were 47900 telephones in the U.S. **The FCC** The Federal Communications Commissions is an independent U.S government agency. The FCC was established by the Communications Act of 1934.It regulates international communication by radio, television,wire,satellite, and cable.
