Introduction of the first phonograph

Phonograph, the first device for recording and reproducing sound, was invented by Thomas Edison and introduced on November 21, 1877.

The first phonograph recorded on tinfoil around a grooved cylinder. Despite its limited sound quality and that the recordings could be played only a few times, the phonograph made Edison a celebrity.
