Answer: The phonograph was developed as a result of Thomas Edison's work on two other inventions, the telegraph and the telephone. In 1877, Edison was working on a machine that would transcribe telegraphic messages through indentations on paper tape, which could later be sent over the telegraph repeatedly. The patent awarded to Edison on February 19, 1878, specified a particular method—embossing—for capturing sound on tin-foil-covered cylinders. The next critical improvement in recording technology came courtesy of Edison's competitor in the race to develop the telephone, Alexander Graham Bell. In 1877, Thomas Edison invented the phonograph using a combination of the phonautograph, the telegraph and the telephone. His goal was to transcribe messages from the telegraph to a piece of paper tape.
