  • 1877: Thomas Edison files for a patent on the phonograph. The idea came to him while working on a telegraph transmitter, when he noticed that when the tape of the machine was played at high speed, it gave off a noise resembling spoken words. After experimenting with a needle attached to the diaphragm of a telephone receiver to prick paper tape to record a message, his idea evolved to using a stylus on a tinfoil cylinder.
