On 21.11.1877, Thomas Edison from America, announced his invention of the Phonograph. The phonograph, record player, or gramophone is a device that was most commonly used from the late 1870s through the 1980s for playing sound recordings. The recordings played on such a device generally consist of wavy lines that are either scratched, engraved, or grooved onto a rotating cylinder or disc.
